THE SPUNKY LITTLE STORM THAT COULD.....
The perfect combination of factors created an unusual storm system yesterday that stalled over the southernmost portion of the state, dumping significant amounts of rain across a relatively small portion of Southern California. Everything south and east of the red dotted line (below) experienced a long duration rainfall event, with periods of heavy rain later Monday afternoon and into the evening hours. Everything north and west of the red dotted line was much drier, with very little rainfall reported from LA to the west and north.
Several daily rainfall records were broken, including:
- San Diego Airport: 2.34"
- Escondido: 4.03"
- Alpine: 2.43"
- Palm Springs Airport: 1.17"
PALM SPRINGS ACTUAL SEASONAL TOTAL (From October 1, 2016 - present): 6.97" (3.13" above normal)
PALM SPRINGS AVERAGE (October 1 - present): 3.84"
PALM SPRINGS LAST YEAR (October 1 - present): 2.45"
Snowfall on the highest peaks above 7,000 feet occurred last night. A quick glance at the cams atop the PS Tram and Toro Peak (south of Palm Desert) reveal a fresh coat of snow.
The intense rainfall caused the San Diego River to flood late yesterday and into today, cresting around 14.15 feet at 3:00 am this morning. Several areas near Mission Valley flooded, including roads and parking structures. The Flood Warning continues this afternoon but the water is receding.
Many reservoirs in the San Diego area have been forced to release water, as they have completely filled up to bankful, including Otay Lakes, and Lake Poway. Here are a few articles describing the water situation in the San Diego area:
This water year has beaten expectations thus far, and the rainy season isn't over yet. Take a look at the drought maps from now, as compared to the same period in February 2016, one year ago:
As you can see above, 2017 has removed all of California from extreme and exceptional drought designation. The areas marked in white are no longer even considered in drought conditions. The small sections of the state that still need more water in order to make up for the multi year deficits, marked in yellow or orange, have greatly improved from 2016. Now, only a few small sections of the state near Santa Barbara and in the Imperial Valley are considered "moderate or severe drought". The areas in yellow are considered "abnormally dry" - which means a bit more rain is needed in order to catch up to the deficits - have continued to shrink in California and most of the rest of the West. The exception to this appears to be the eastern plains of Colorado and New Mexico, where dry conditions have prevailed since October.
SUNNY WEATHER RETURNS TO THE DESERT
Despite the water woes, the sun returned to the desert today. The weather will become progressively warmer each day this week, warming into the 70's and likely above 80 by Friday. Some wind may occur over the weekend, as a weak system moves in to our north, and some clouds may blow through. The deserts are still expected to be dry over the weekend, despite some cloudiness and moist air returning to the coastal and mountain areas to our west around Sunday or so. Temperatures may rise to the lower 80's by early next week in the desert. Long range forecasts show the remote possibility of a system moving into our area after Wednesday or Thursday of next week. It's still too early to predict if the storm will bring rainfall to our area or not.
Blue skies and warm weather will help sprout more greenery on our hills and help produce what will undoubtedly be a fantastic wildflower season this year.
