Due to the current heavy rain, several areas are experiencing different degrees of flooding, with potential road closures. We urge community members to use caution, follow posted detours, and avoid driving or walking through flooded roadways. Standing water can be deceiving and may be deeper than it appears. 

The only road closure at the moment is east/westbound 42nd

If you have to go out, drive safely San Mateo and stay dry.
