The San Francisco Department of Public Works is also prepared. They're giving away sandbags.
TIPS: How do you recover from hydroplaning?
The sandbags are available for pickup 8 a.m. to 2 p.m. Monday through Saturday at Marin and Kansas Streets. They weigh 40 pounds and are free for San Francisco residents who can pick up as many as 10.
Public Works is also prepared for high winds.
"We do have tree crews that are on standby. We know when there's water on the ground and there are high winds trees are more prone to failure. So, we want to be able to get out of there quickly remove any trees that may be down or big branches that are down," said San Francisco Public Works Spokesperson Rachel Gordon.

Public Works also wants to encourage residents to do their part from trimming trees on your property to picking up trash and debris.
