- Camino Del Este between Station Village Drive and Camino De La Reina;

It was unclear when the roadways will reopen, with city officials saying the city's Stormwater Department will monitor the flooding. Drivers were advised to follow posted signage and avoid flooded areas.
The rains are expected to bring up to 7 inches in the mountains, 3 to 6 inches in the valleys and 2 to 3 inches for the coast, according to the NWS flood watch.
A colder system from the northwest is expected to bring additional precipitation late Saturday into Sunday with precipitation amounts being much smaller, according to the NWS said.
Forecasters are also calling for a chance of snow overnight Saturday at about 5,000 feet.
