A Pacific storm and atmospheric river will impact the Pacific Northwest states and northern Rockies this weekend, bringing locally heavy low elevations rain and heavy high elevation snow in the mountains. By Sunday over the Interior Northwest, rain combined with snowmelt will increase the risk of flood hazards. Flood Watches are in effect. Read More >

Leading up to the meteorological winter of 2016 , which begins on December 1, the long range forecast looked grim. The Climate Prediction Center was forecasting equal chances for above/below normal rainfall and warmer than normal temperatures for the Bay Area. The forecast fits the general thinking for a La Nina winter, warm and dry. (Official CPC outlook can be found here) So, when meteorologists see rain in the numerical weather prediction models it's a welcomed sight. However, too much rain in a short time period can cause problems. That statement is especially true following a notable wildfire season with dangerous burn scars. Several days in advance of December 15, it began to look like this storm would be rather potent bringing periods of heavy rain and gusty winds, which ultimately resulted in flooding, landslides/debris flows and numerous downed trees. From a meteorological standpoint, a potent frontal passage combined with a moisture rich airmass would be items of concern. Additionally, the surface pressure gradient would tighten leading to very gusty winds, which would result in hazardous conditions on the waters and downed trees over land. One may ask, "Why the very moisture rich airmass"? Two words, Atmospheric River. Leading up to the event, numerical weather prediction models showed a plume of very moist air streaming in from off the Pacific Ocean (Atmospheric River). For detailed information on Atmospheric Rivers visit this website. This particular type of Atmospheric River is known as a "Pineapple Express" because the moisture source region can be traced to the vicinity of Hawaii. Below are two images, one is a numerical weather prediction model showing integrated water vapor transport and the second is satellite imagery showing the moisture tap or AR taking aim at the Central Coast. Both images clearly indicate ample moisture streaming toward the California Coast. Lastly, derived satellite imagery (not shown) revealed the moisture on detected on satellite was over 200% of normal. Simply put, lots of moisture was headed toward California. Numerical weather prediction models also predicted strong winds would be possible ahead and during the frontal passage. Wind gusts up to 50 mph were being forecast along the coast and higher terrain. In summary, two weather impacts of concern were flooding and damaging winds. Therefore, a Flash Flood Watch was issued for the Loma/Soberanes Burn Scars and a Wind Advisory for the coast and hills (see graphic below). By the evening of Wednesday, December 14, the storm system began to knock on the Bay Area's doorstep with light warm frontal rains. Initially rainfall was relatively light with greatest amounts over the North Bay and coastal mountains ( a few tenths of an inch). The heavier rainfall began to develop along the cold front by early Thursday, December 15, before slowly progressing southward through the Bay Area on Thursday. The "slow" movement and moderate to locally heavy rainfall led to numerous reports of flooding, especially the North Bay. (see below for complete list of flooding reports). Flooding impacted many locations causing damage to cars and properties (see photos below) In fact, even the larger rivers began to fill up with the Russia River forecast to reach minor flood stage (see below). One major area of concern were locations/residents in and around the burn scars from the Loma fire and Soberanes fire with possible debris flows. As the event unfolded and rain rates increased over the burn scars a Flash Flood Warning was issued. (see graphic below). In the end, storm total rainfall (see graphic) ranged from a few tenths to over seven inches. The North Bay Mountains/Valleys, Santa Cruz Mountains and the Santa Lucia Mountains ended up receiving the most rainfall. For complete rainfall totals see the information statement below. The much advertised gusty winds also verified with numerous reports of wind gusts greater than 50 mph. For a detailed list of wind gusts see the information statement below. The gusty winds also brought down drought stressed trees damaging power lines and cars. (see photos below) |
