Light rainfall is expected to linger in parts of San Diego County this morning as the second of two wet winter storms that drenched the region this week moves out of the area.
A National Weather Service flood warning remains in effect for the San Diego River, which crested at 14.15 feet at 2:15 a.m. On Monday night, San Diego police advised nearby residents, especially in homes that have been affected in the past, to monitor the rising river, and to be aware of fallen trees and road closures.
“Current forecasts suggest flooding of several area roadways, the parking garage, golf course and a few lower lying businesses,” according to the weather service. “Expect added travel delays in the area.”
Forecasters said the river levels should fall to below flood stage this afternoon, but it could take until tonight to decrease to below the level of low water crossings.
