Good morning, Central Coast!

We are waking up to heavy rain that made its way to most of central and southern California overnight.

The main concerns for this forecast will be the heavy rain (with possible thunderstorms Tuesday afternoon), strong winds, and heightened snow fall.

Rainfall totals still call for 1-3 inches across the csts/vlys with 3-6 inches across the foothills and mountains 
through Wednesday night. Rainfall rates will generally range between 0.25 0.50 inches/hour, but local rates of
0.50-1.00 inches/hour will be possible this morning with the front and associated with any thunderstorm activity. 

A flood watch is in effect for the area due to the anticipated rain and already saturated grounds. Coastal flooding is possible at hightide and there is a high surf advisory in place until Thursday.
