A large Pacific storm will move ashore early Thursday and smack San Diego County in late morning, dropping heavy rain in some areas and likely triggering flash floods across the region, the National Weather Service said.
SeaWorld has announced that it will be closed on Thursday due to the combination of rain and high winds.
Forecasters say that San Diego will get between a half-inch and one-inch of rain from the system by Friday morning. Rainfall is expected to be higher further north, and across inland areas.
Some inland foothills and valleys could get up to 1.5 inches of rain, said Brandt Maxwell, a weather service forecaster. The mountains could experience upwards of three inches of precipitation.
The system will produce gusty winds at the coast and in the mountains. It also has produced major swell that could generate 10-12 foot waves in some spots in South County on Thursday. But the waves will be roughed up by the winds
The entire coastline will experience dangerous rip currents.
The rain will taper off on Thursday afternoon. But more rain is expected on Saturday.
