The central San Joaquin Valley may receive some rain Sunday night as Hurricane Norbert moves north from Southern California.
Clouds and a possible thunderstorm are expected in the Fresno area around midnight, said meteorologist Carlos Molina of the National Weather Service office in Hanford. He said the hurricane will bring with it a 20% chance of rain.
The clouds and moisture will continue into Monday morning before being pushed east into the mountains near midday, Molina said.
Due to the hurricane, strong winds are also expected to pick up in the mountain ranges. Molina said those driving along Interstate 5 should exercise caution.
Farther south, the weather service issued a flash flood watch for mountains in Riverside and San Bernardino counties, as well as inland areas of San Diego County. Thunderstorms are expected with possible lightning. Rains could be heavy enough that flash floods might develop, the NWS said.
"Given the moisture content of the atmosphere, there is potential for isolated rainfall amounts near or exceeding three inches," the weather service said.
