A flood warning has been issued for Los Angeles and surrounding Santa Barbara and Ventura counties National Weather Service (NWS) on Thursday, which will remain in effect through the night.
According to the official website of the NWS Los Angeles, a flood watch was in effect from the evening of Wednesday, December 31st and will last until the night of Thursday, January 1st.
Possible impacts and how to stay safe
The NWS says the flooding may lead to an increased risk of rockslides and mudslides, and has asked travelers to avoid canyon roads and mountain roads.
There is also a moderate risk of flooding and debris flows. The NWS strongly advises residents in the area not to cross flooded roads. It is better for travelers to adjust their travel plans accordingly and also pack extra supplies as needed.
Residents, and especially campers, should also stay away from rivers and streams as strong currents are forecast in waterways.
Cars should be parked away from tall trees and boats should be kept in safe harbors as there is a high risk of falling trees and rough seas.
The most likely scenario by Thursday (January 1) night
The peak of the flood watch is Thursday from 2:00 a.m. to 6:00 p.m. Maximum rainfall rates are expected to be 0.25-0.50 inches per hour, while isolated rainfall rates are likely to be 0.5-1.0 inches per hour.
Total precipitation is expected to be 1.0 to 2.0 inches, with 2.0 to 5.0 inches expected in the mountains and foothills.
Wind gusts are expected to reach 20 to 40 km/h. Local winds are expected to reach 40 to 50 mph.
Steps to follow while riding in rain:
1. Make sure your headlights are on, even during the day. This improves visibility and reduces the likelihood of accidents
2. Stay on high ground and drive in the middle lanes if possible.
3. Do not approach large vehicles as they may throw down water showers that reduce visibility.
