Pineapple Express returns with much needed rain for the West Coast

With a title like that, it sounds like a train doesn't it? Well, it's intended to. The wave of moisture heading toward the West Coast is basically a firehouse of moisture that comes up from the Tropical regions southwest of Hawaii, flies right through the island chain, and then straight to the U.S. It is very clearly seen on this satellite imagery below.


The massive moisture flux is due to the sub-tropical jet stream moving further north into the Southwest U.S. These" atmospheric river" events as they are usually called are typically responsible for more than 70% of the annual moisture that falls in California every year. This is FANTASTIC news for the state because they just finished one their driest January's on record. In fact, San Francisco recorded its first completely dry January since records began nearly 150 years ago. Obviously, the state is still in a massive drought…



But relief is in sight, well at least for central and northern California as widespread amounts of 3-12" are expected, with locally up to 18" of rain in the northern California Mountains through the weekend. Here is the forecast for the next 5 days.


Too much of a good thing is possible through Monday with flash flooding and mudslides possible north of San Francisco. Doesn't look like LA or San Diego will benefit much from this event which are the areas that need it the most. I guess beggars can't be choosers at this point.
