Press Enterprise:

In coastal and valley areas, Los Angeles and Orange counties are expected to get 2 to 4 inches of rain between Thursday and Sunday, while Riverside and San Bernardino counties should expect 2 to 3 inches. As with other storms this season, areas farther north are expected to get more rain, said National Weather Service meteorologist Derek Schroeter.

The heaviest rain is expected to fall on mountain slopes facing south and west – up to 5 inches in the Santa Ana Mountains and potentially even more in the San Bernardino and San Gabriel mountains.

Be careful friends!!
