The strongest flood warnings from the National Weather Service are for the Orange County canyons. The morning update on the Los Angeles situation from Mayor Villaraigosa's office:
The next round of storms are scheduled to arrive around 12pm today and remain until 6pm. Rainfall is expected to average approximately .5"-.75" per hour.
By Friday, a total rainfall is expected to reach 4-8 inches in Coastal and Valley areas, 8-16 inches in the Foothill areas, and up to 20 inches in the burn areas (South Facing Coastal Slopes). The cumulative affect of these storms will bring threats of significant flash flooding and debris flow in the burn areas, and the threat of urban and small stream flooding and rock slides in other areas.
The entire City of LA is currently under a flash flood watch. The most recently issued flash flood watch was for downtown LA.
