Series of strong storms will bring heavy precipitation to the west coast
Posted by Lindsey Ozment on November 28, 2012
The west coast will continue to experience heavy rainfall today and through the weekend as a series of low pressure systems continue to move through the area.
At this time a low pressure system is starting to impact the west coast, extending from California to southern Washington. As it edges along the coastline, rainfall will continue to occur while this storm rotates a lifts to the north throughout the day. Northern and central California can expect precipitation amounts today around 1/4 of an inch to 1 1/2 inches, with activity peaking around mid afternoon before subsiding slightly this evening.
As this system begins to lift, plenty of moisture will be in place before another stronger low pressure system moves in beginning on Thursday. This second low pressure system will remain quasi-stationary for the next few days before lifting into the Alaskan Gulf, resulting in a shortwave trough moving onshore.
Precipitation totals from today into Monday will be substantial. Northern California is expected to receive the most rainfall, with totals reaching up to 15 inches. Farther north along the coast, in Oregon and Washington, places such as New Port, OR and Seattle, WA could see rainfall totals anywhere from 3 to 6 inches. Snowfall should be expected in areas of higher elevation, especially along the Sierra and Cascade ranges. Periods of moderate to heavy snowfall are possible today through the weekend in northern California, mainly for areas above 4500 feet, where totals could be anywhere between 4-8 inches per day.
Winds of 35-45 mph will continue to be strong through the weekend with these storms, and with the large amounts of rainfall, conditions will continue to become very dangerous. As the week progresses, the potential for flooding will increase as well. We will continue to monitor the situation closely, and update the blog with more information as this situation continues to develop.
