Los Angeles, California – A flash flood watch is in effect for much of Southern California this week as significant rainfall is forecasted, raising concerns over burn scar areas affected by January wildfires. The weather system is expected to begin moving into the greater Los Angeles area starting Monday night, potentially bringing 1.5 to 3 inches of rain by Wednesday morning.
Rainfall is forecasted to start around 10 or 11 p.m. on Monday, initially affecting areas north of Los Angeles County. Overnight rainfall is anticipated to intensify into Tuesday morning, with stronger showers predicted particularly in the Eaton Fire burn scar regions between 5 and 10 a.m. Following this, light to moderate rain is expected to persist throughout Tuesday.
This storm system, characterized as an early season storm and described as “widespread and beneficial,” may also produce thunderstorms, hail, and strong rotating winds, with some potential for tornadic activity on Tuesday. Rainfall rates could reach 0.25 to 0.50 inches per hour and may be even higher if thunderstorms develop, increasing the risk of flash flooding.
Evacuation warnings have been issued in areas recently affected by wildfires, particularly those with burn scars, as heavy rain could lead to debris flows and landslides on hillsides. Communities in Los Angeles County, as well as regions of Orange and San Bernardino counties, are at heightened risk due to these conditions. Forecasters are urging residents in these high-risk areas to remain vigilant and prepared for potential emergencies.
As for the temperature forecast, Los Angeles and Orange counties can expect a high of 69 degrees and a low of 57 on Monday. Valleys and the Inland Empire will see a high of 73 degrees, dropping to 62 degrees on Tuesday. Coastal beach areas are projected to reach a high of 69 degrees and a low of 61 with sunny conditions on Monday, while mountain areas will face a high of 55 degrees with a low of 26. Desert areas are forecasted to have a high of 70 degrees and a low of 50 on Monday. Notably, Palm Springs could experience a high of 84 degrees before taking a significant drop to a projected high of 60 degrees on Tuesday.
The storm system is driven by a low-pressure area from Oregon, which will bring scattered showers beginning Monday evening. It is anticipated that precipitation may continue into Wednesday, with final showers expected to depart the region by Wednesday afternoon. Throughout the incoming storm, winds are projected to increase in strength, particularly in desert areas, with gusts reaching between 20 to 55 mph.
This precipitation event comes as Southern California continues to grapple with severe drought conditions, which the coming rain is expected to alleviate, albeit partially. Most of the region is currently suffering from months of dry weather, making this forecasted rainfall a crucial weather development.
As the region prepares for the incoming storm, residents, particularly in vulnerable areas, should stay informed about local weather updates and heed any evacuation orders as necessary. Local authorities will likely continue to monitor conditions closely and provide updates as the situation evolves.
