Los Angeles, California – A significant storm is forecasted to bring widespread rain to Southern California, starting late Monday and continuing into Tuesday. The National Weather Service has issued a flash flood watch for much of the region, set to take effect at 5 a.m. Tuesday and lasting through 5 p.m. Rainfall totals are expected to reach between 1.5 to 3 inches by Wednesday morning, with rainfall rates potentially hitting 0.25 to 0.50 inches per hour, particularly in areas affected by recent burn scars.
Evacuation warnings have been issued for several high-risk areas in Los Angeles County, including Pacific Palisades, Altadena, Sylmar, and Hollywood Hills. Residents in these zones are urged to take caution and prepare for possible mudslides and debris flows. The storm is expected to bring additional challenges, including strong winds with gusts that may reach up to 60 mph, especially in desert communities.
Tuesday’s weather will feel considerably cooler, with high temperatures predicted to be around 63 degrees, significantly lower than the normal for this time of year. Furthermore, isolated thunderstorms may develop, creating the potential for hail, strong winds, and even localized tornadoes in some areas.
Temperature Drops and Storm Impact
Following the storm, cooling temperatures are expected to continue into Thursday, with the possibility of the first fall freeze appearing in some inland areas. This storm marks the first significant rainfall in months for many parts of Southern California, coming after a dry spell that has contributed to severe drought conditions across the state.
Official Weather Updates and Safety Precautions
The National Weather Service advises residents to stay vigilant and monitor official weather updates, particularly if they are in areas prone to flooding or mudslides. Given the forecasted intensity of the rainfall and wind, authorities recommend that individuals plan ahead and take necessary precautions, especially in burn scar regions, where the risk of adverse weather impacts is heightened.
Background on Drought Conditions
Southern California has experienced a prolonged dry spell, leading to drought stress for both the environment and agricultural sectors. This upcoming storm is seen as a critical event that could aid in alleviating some of the region’s drought issues, although it also brings with it increased risks for flooding and landslides in susceptible areas.
Residents are urged to remain aware of their surroundings, avoid driving through flooded roads, and seek higher ground in response to weather advisories. The weather system’s full impact will be assessed in the days following its passage, as officials evaluate damage reports and assess overall conditions in the wake of the storm.
