4 Inches Of Rain Possible In San Mateo County

SAN MATEO COUNTY, CA — Up to 4 inches of rain could drench coastal areas by the end of the week, the County of San Mateo told residents in a message Wednesday, while providing safety tips on dealing with the current winter storm.

Prepare your home:

• Secure outdoor furniture.
• Keep emergency supplies handy.
• Check on neighbors.

"Heavy rains can cause flooding and erosion and sweep away topsoil, mud, plant material and debris off," the county warned.

Sandbags are available in unincorporated areas and for residents within cities. Be prepared to assemble and load the sandbags yourself.

On the road:

• Reduce speed - give yourself a 5-10 mph buffer below limits.
• Turn on headlights - improves visibility.
• Double your following distance (at least 4-5 seconds).
• Avoid puddles that hide potholes.
• Never drive through flooded roads. It takes just 12 inches of rushing water to carry away most cars, and just 2 feet of rushing water can carry away SUVs and trucks.
• Postpone unnecessary travel during the heaviest rainfall.
• If hydroplaning: ease off gas, don't brake suddenly, steer straight.
