Periods of moderate to heavy rain Saturday night through Sunday morning on our already saturated soils could lead to flash flooding of streams and rivers, and in local urban areas.
Winds could exceed 40-50 mph and will be strongest near the coast and in higher elevations.
The storm system that has been heavy at times since Wednesday, and brought lightning and thunderstorms, is expected to continue through Monday.
Friday’s forecast calls for showers and possible thunderstorms that could produce heavy rainfall. Winds could gust as high as 24 mph and we could see between a tenth and a quarter inch of rain.
All in all, Palo Alto could get a total of about two inches of rain by Sunday. So far this month, Palo Alto has received 4.64 inches of rain. The average historically has been 2.97 inches of rain in January.

San Francisquito Creek Update as of Thursday, Jan. 19, 2017
The National Oceanic and Atmospheric Administration (NOAA) River Forecast Center is currently predicting 0.8 inches of rain in the San Francisquito Creek watershed on Saturday night through Sunday morning. A peak flowrate of 1,430 cfs is estimated to occur on Sunday at 11 am. The predicted flowrate is far below the creek capacity. On Saturday, a moderate high tide of 5.9 feet is predicted at about 8 p.m. A higher tide of 8.3 feet is predicted at about 8 a.m. on Sunday.
The City will continue to have crews closely monitoring the San Francisquito Creek levels throughout the storms, and the creek monitor sensors are fully functioning again after experiencing a technical problem with the communication system that reports the field data.
You can also monitor Palo Alto's creek levels here.
