Bay Area Weather: Three Storm Systems in Three Days

Three storm systems. Three days.

That's the expected weather report starting early Tuesday through Thursday.

Here are the highlights of what you need to know:

Early Tuesday: The heaviest rain and gusty southerly winds between 20 to 40 mph arrived Tuesday between 1 a.m. to 7 a.m. The highest accumulations will pound down over the North Bay, including Mill Valley where a downed tree took down a utility pole, causing a power outage for about 200 PG&E customers.

From 8 a.m. to 3 p.m., Bay Area residents should expect scattered rain with isolated thunderstorms, according to the National Weather Service. Rain totals will range from half an inch to 1.25 inches.

Wednesday morning: Another fast moving cold front will blast through the Bay Area between 4 a.m. to 9 a.m. with wind gusts between 20 mph to 50 mph. Isolated tree damage and few power outages are possible with the quick succession of these storms and saturated ground. Totals will range from half an inch to one inch. The highest concentrations will be in the Santa Cruz mountains and coast.

Thursday: The rain system will be the weakest of the storms bringing in scattered precipitation from 10 a.m. to 4 p.m. and rain totals of .10 of an inch to half an inch.

The storms follow on one previous rain system stemming from the weekend, giving the Bay Area a total of four storms over the course of one week.
