Six on Saturday: When It Rains, It Pours

 

The frequency and duration of rainy weather here is not very much more than in the rain shadow where the inland base of the Santa Cruz Mountains merges into the Santa Clara Valley. However, the volume is about triple! My former neighborhood in town just about fifteen miles away gets about one foot of rain annually. The average annual rainfall here is about three feet.

That extra two feet sometimes seems to fall all at once.

1. Rain got heavy enough for me to bother recording this first of six brief videos. I do not know why the lights upstairs were pulsating and blinking. The downspout seems to be jet propelled.

2. This was certainly more than I expected. Off to the left, there were only two sandbags to put in front of a doorway that is three sandbags wide. This was a major problem. I did not panic.

3. Now I panicked. I called for help, but my radio was too wet to operate. There was nothing anyone could do anyway; or so I thought. I stopped the camera and went upstairs to investigate.

4. Removal of debris from the grate over this drain fixed everything fast. This was more than I expected too. We all know that this drain is partially clogged. The water and hail was freezing!

5. Within a minute or so, the water drained away surprisingly efficiently, leaving this icy mess on the small patio between the two stairways. It was like a Slurpee mixed with redwood debris.

6. More of the grungy Slurpee remained on the lower patio outside the doorway that lacked adequate sandbags. Water barely crossed the threshold to dampen a few square inches of carpet.

Rain Shadow

P91222Hollywood is famous as the Cinema Capital of the World. Niles was its predecessor. Both are within regions of remarkably diverse scenery that is so important to cinema. Mountains, deserts, chaparrals, forests, lakes and big cities are conveniently nearby. There are not many places in the World with such a thorough mix of geography and climate. California really does have it all.

It is a challenge for gardening though. The stone fruits that grow so naturally in the Santa Clara Valley are not quite as productive just a few miles to the South in the Santa Cruz Mountains. The pears and apples that do so well in the Santa Cruz Mountains are not quite as happy in the Santa Clara Valley. Species that want a good chill in winter do not want to be in Los Angeles.

On the coastal side of the Santa Cruz Mountains, just outside of Felton, a few days of rain filled the bin in the picture above. The rain continued just as long throughout the area, including the inland side of the Santa Cruz Mountains and the adjacent Santa Clara Valley. Although the duration of the rain was approximately the same, the volume of precipitation was very different.

The water in the bin is more than a foot deep. That is about the average annual rainfall for my former neighborhood at about this same elevation, but on the opposite and inland side of the Santa Cruz Mountains. Storms must drop much of their moisture to get up and over, but are then able to retain much of the remaining moisture as they drop in elevation on the other side.

The drier inland side of the Santa Cruz Mountains, and adjacent portion of the Santa Clara Valley are in what is known as a ‘rain shadow’.

Rainy Season

 

 

As I mentioned this morning, the first storm since spring delivered a bit more than an inch and a half of rain before dawn on Wednesday, ending the fire season. The second storm is here right now. It is expected to be followed by a continuous series of storms that will provide rain through Monday, showers through Thursday, more rain on Friday, and showers . . . forever!

It is now the rainy season.

The video above shows what rain does. It gets things wet. It is, after all, composed of water. It falls mysteriously from the sky, which, as you can plainly see, is occupied only by a mostly monochromatic gray cloud cover. Seriously! There is nothing else up there. There is no one on the roof with a hose or anything of the sort. All that water just falls from the cloud cover above.

I could not get video of individual raindrops falling. They are too small and too fast. Only a few can be seen indirectly in the video, falling in front of the water cascading from the rusted out gutter. The spots on the video are raindrops that landed on the lens, so were no longer so animate. The cascading water is, of course, an accumulation of many raindrops that fell on the roof.

Besides ending the long fire season, rain also disrupts the slim fall color season, when foliage of certain deciduous trees turns color as the weather cools in autumn. There is not much to brag about anyway. Only a few native trees are moderately colorful. More colorful exotic trees are not very popular because they do not color as well as they do where autumn weather is cooler.P91130K

Before the rain, these birches were a nice clear yellow, but were already defoliating. Their fallen leaves were as pretty on the ground as they were in the trees, but unfortunately needed to be blown. By now, there is likely more on the ground than there is in the trees, but it will need to be blown too. At least it gets to stay on the open ground in the rest of the casual landscape.P91130K+

The only tulip tree here got cool enough to defoliate before the birches this year, but not quite cool enough to color well first. It is a grand tree nonetheless. We do not expect exemplary color in autumn in our splendidly mild climate anyway. The sweetgums will compensate. They are only beginning to color, and should hold some of their foliage rather well through the weather.P91130K++

Six on Saturday: First Storm

 

The first storm since spring came through Tuesday night. It was cool enough for a bit of snow on the summits of the Diablo Range, including Mount Hamilton, east of the Santa Clara Valley. The fire season is now over. More storms are forecast. More will continue through the remainder of winter and into spring. Even chaparral climates eventually get a seasonal ration of rain.

1. An inch and a half of rain is generous for a first storm. It is more than 10% of what my garden in town got annually. This side of the Santa Cruz Mountains gets about three times as much.P91130

2. My reflection in the rain caught in this ‘tote’ is not as artistic as it was in the green bucket last year. I tried. A flash would have added interest. I do not really know how the camera works.P91130+

3. Cyclamen, even the common florists’ type, deserve more than to be grown as cool season annuals, and then discarded in spring. I can rant about that later. For now, they sure are pretty.P91130++

4. After the rain, even a close up of this seriously abused juniper is pretty. It was recycled from one site into another, only to be removed again. It is now canned and waiting for a new home.P91130+++

5. Storms are messy. There was not much wind with this storm. Nonetheless, rotten limbs get heavier and softer as they get soaked by rain. This one broke apart more as I dragged it away.P91130++++

6. What is worse than runoff from the road washing away some of the yellow birch foliage dislodged by rain, is that it likely took away some of the amaryllis seed tossed out here earlier.P91130+++++

Almost RAIN!

P91123KThere have been only three hints at precipitation since last spring.

The (sideways) picture above shows the same dampened hood of a Chevrolet that provided the illustration for a post on another blog on September 30.

The picture below shows a similarly dampened but different windshield from that which provided the illustration for a post on November 16, regarding a bit of precipitation two days prior, on November 14.P91123K+

All four pictures here were actually taken just after a very brief rain shower that happened just after midnight on November 19. I tried to be artistic with them, but I am not a photographer.

The picture below demonstrates how difficult it is to hold the camera steady while getting a close up picture of rain dripping from a lumber rack at night. Do digital cameras automatically extend exposure to accommodate for the darkness? Is it blurred or merely ‘abstract’?P91123K++

The rain shower was very brief, lasting only a few minutes, but dropped dozens of individual raindrops, maybe more than a hundred! In fact, there were enough of them to collectively flow from one of the roofs, accumulate in a gutter, and flow down this downspout and onto the pavement below! (I really do not know why a diverter is needed on pavement, but there it is.)P91123K+++

I bet that if all the precipitation than fell from the sky during these last three incidents could have been collected, there would have been more than a pint! As excellent as it was, it was not even the best of it. For the first time since last spring, a storm is predicted to move in and start RAINING about noon on Tuesday, November 26! Showers should continue afterward.

The rainy season will likely begin with this first storm. That is how the weather typically operates here.

Not Quite Rain

P91116KMost of us here agree that the minimal bit of precipitation that fell from the sky on Thursday was not real rain. There are a few different theories about what it actually was though. It could be considered to have been drizzle. It alternatively could have been heavy fog or mist. Some of us make up silly names for what it was, such as fine rain, dusting, spritzes, sprinkles or mizzle.

Is it just me, or do those last three sound like inane kitten names? ‘Dusting’, sounds dirty and dry, which it was not.

Whatever it was, it was the second occurrence of such precipitation since the rainy season ended last spring. Something similar happened on the last day of September. I wrote about it in my other blog, with a picture of it on the hood of a parked car, rather than the windshield. I think it was more of a surprise then because it was earlier, and the chance of precipitation was slim.

This weather pattern is still within what would be considered normal here. The rainy season typically starts a bit earlier, even if with just a single primary storm passing through, followed by a long pause before more follow. There is no strict schedule though. We know that the rain will eventually start, and that rainy seasons that start late tend to provide significantly more rain.

Rain is likely just as uncomfortable here as it is everywhere else. Perhaps it is even dirtier, because it rinses off dust and crud that has been accumulating since spring. No one wants to work in their garden while it is wet. Nonetheless, because there is no rain for nearly half the year, the first storm of a season is something to be celebrated. The forecast predicts no celebration yet.

Splat!

P90310There are a few consequences to all this excellent rain. Gutters are flooding. Trees are falling. Mud is sliding. As much as we should be grateful for what we are getting while we are getting it, it is getting rather old. Clear and sunny weather that is forecast after today will be a welcome relief from all this muddy sogginess.
Almost all of the flowering cherries have somehow postponed bloom. It has not been unusually cold. It is as if the trees somehow know better than to bloom while so much unusually heavy rain is falling. Otherwise, they might have bloomed only briefly before the blossoms got knocked off. The buds are so fat that I expect they will begin to bloom by the middle of the week.
Only one flowering cherry that always blooms significantly earlier than the others bloomed on time, and is already finished. Considering how heavy the rain was during that time, the light duty bloom actually lasted impressively well.
Daffodils tried to delay their bloom as well; but some could wait no longer. Many were not bothered by the heavy rain. Others were knocked flat, and needed to be propped with small hoop stakes. Only some of those that were planted late in the planting season kept their buds closed this late.
I should be pleased that these hyacinth bloomed at all this year. They are the sort of bulbs that bloom only once in their first year, but then do not get sufficient chill in winter to bloom again. They must be in a cold spot. Unfortunately, it is also a shady spot. The floral stems stretched so much in the shade that they were easily knocked down by the heavy rain. Now they lay there like they have fallen and can’t get up.

Looks Like Rain

P90202KSupposedly, all this rain has not been too terribly excessive. It seems to have been raining more frequently than it normally does, with only a few days without rain in between, and more often, many consecutive days of rain. The rain also seems to be heavier than it normally is. Yet, the total rainfall is not too much more than what is average for this time of year, and well within a normal range.
The volleyball court at Felton Covered Bridge Park looks more like a water polo court at the moment. The pair of ducks out of focus on the far side seem to dig it. The water is not as turbulent at it is the San Lorenzo River where they live.
Speaking of the San Lorenzo River, it has been flowing very well and at a relatively continuous rate. It came up high only for a short while. None of the heaviest downpours lasted long enough to keep it very high for very long. The ivied log laying in the river in the middle of the picture below was an upright cottonwood tree only recently, but fell into the river as many riverbank cottonwoods do when the ground is softened by rain and higher water.P90202K+
When things get as soggy as they are now, this great blue heron strolls the lawn at Felton Covered Bridge Park, probably because the San Lorenzo River is too turbulent, and also because the worms that live in the lawn come to the surface as the lawn gets saturated. He or she is never in a hurry, but just strolls about slowly, occasionally prodding the muddy soil. However, when it wants to move fast, it is quick enough to catch small frogs. Supposedly, this great blue heron caught and ATE a small gopher!P90202K++

Six on Saturday: Another Day At The Office

 

There is no rush to leave the office and shop when the weather is cold and rainy. We have been getting quite a few of the inside chores done. When we do go out in the rain, I do not like to take the camera out from under my rain gear; so I do not take many pictures. Besides, since most of my work involves pruning right now, I have not been working much around what is blooming or other interesting subjects.

1. Sitka spruce brought back from near Smith River within their native range are now happily canned in the recovery nursery at our shop. They look as if they were grown here, or are on a bench in a production nursery. They will eventually go out into the landscapes.P90302

2. Staghorn fern that the same colleague with the Sitka spruce brought back from his grandparents’ home in Orange County are not so happy. They were desiccated on arrival. Now that they are getting much more rain then then need, they are just rotting. The specimen that is still attached to the plywood on the left is probably beyond salvage. The specimen that broke its wire and fell onto the deck to the right is only partially viable. The viable portion will probably be separated from most of the rotting necrotic portion when it is attached to a new slab.P90302+

3. Colorado blue spruce and a young coast live oak are adjacent to the deck where the Sitka spruce and staghorn fern reside. This is not a good picture, but shows how the young oak to the left is crowding the older spruce to the right. Their main trunks are only about two feet apart at grade. The spruce was planted back in the middle of the 1980s, and would be a more desirable tree, but is very distressed, and is not likely worthy of salvage. The native oak grew from seed within only the past several years, and is not particularly remarkable, but happens to be quite healthy and well structured. It is not easy to decide which tree to cut down. I sort of suspect that the oak will win, and the spruce will need to go. Those are cruddy box elders in the background.P90302++

4. Bucket of rain water is impressively full next to the spruce and oak . . . and other spruces and staghorn ferns. There is an open recycle bin nearby that is also full. It must have been somewhat dark rather early in the morning for the flash to operate when I took this picture. I do not know if it ruined my selfie or just made it more artistic.P90302+++

5. Wild plum is still blooming in some spots. These survived all the rain rather well by delaying their bloom somehow. It will be raining again by the time you see this after midnight on Saturday morning, so this bloom will not last long. There may be others that bloom even later though, and with one exception, the flowering cherries have not started their bloom yet. That darkness in the background is the trunk of a big redwood tree.P90302++++

6. Wild plum close up shows the detail of the blossoms, and the unfocused silhouette of the redwood trunk in the background.P90302+++++

San Lorenzo River

P90210It may not look like much, but before all the rain started, the San Lorenzo river was shallow enough here to walk across. The water was clear and barely flowing. It is impossible to guess how deep it is now. It looks like cafe au lait, and is certainly flowing better than it had been. The watershed is less than a hundred and fifty square miles, so all this water is not coming from very far away.
The first picture above, of the San Lorenzo River flowing south to Santa Cruz and the Monterey Bay, was taken from the western of the two windows on the south side of the Felton Covered Bridge. Experts believe this to be the best of the four windows. My Mother has an old black and white picture of my older sister, my younger brother and I looking out from this window when were just little tykes. There was a railroad bridge out there a long time ago. Only concrete foundations remain.
The second picture below, of the San Lorenzo River flowing from the Santa Cruz Mountains beyond, was taken from the western of the two windows on the north side of the Felton Covered Bridge. The San Lorenzo River flows south on this side too!
It has been raining rather well here. Boulder Creek, which is at the far north end of the San Lorenzo Valley, gets more rain than most places in California, and far more than the rain shadow region on the inland side of the Santa Cruz Mountains. Local rain does nothing for the water supply of the rest of California, but is a good indication that snow is falling in the Sierra Nevada, where most of the water for much of the rest of California is stored in the snowpack.P90210+
