Thunderstorms possible as another heat wave scorches Southern California

Temperatures are expected to reach dangerous highs in the greater Los Angeles area this Friday through Saturday as another heat wave grips the Southland.

Southern California valleys, mountains and deserts will experience the highest extremes with temperatures in the triple digits in the lower mountains and interior and between 95 and 105 in coastal valleys, according to the National Weather Service.

Those temperatures could remain in place in the mountains and interior regions through next Wednesday or Thursday. Temperatures will likely dip slightly by then in the coastal valleys, officials said.

Several heat warnings, watches and advisories have been issued for much of Southern California.

Health officials warn of a high risk of heat illnesses, particularly for sensitive populations such as elderly, children and those without access to air conditioning. Residents are urged to make plans to stay cool and hydrated and avoid spending too much time outdoors.

With those rising temperatures also come the possibility of dry thunderstorms, NWS says.

Meteorologists say there’s a 5-15% chance of thunderstorms forming from now to Sunday. Most rain will evaporate before ever hitting the ground, but NWS says thunderstorms could bring some brief heavy rain to the mountains.

Overall, the high heat, low humidity and risk of thunderstorms, in conjunction with what are expected to be gusty winds, will create ideal conditions for wildfires to ignite and grow quickly.

While a Red Flag warning has not yet been issued, there is a slight chance one could be put in place in the driest and windiest areas of L.A. County.

Off the coast, the NWS is warning about the possibility of strong rip currents and elevated surf through next week. Beachgoers are urged to only swim in areas where lifeguards are present and avoid walking along jetties or other rocks near the water’s edge.

Seas are expected to be rough and choppy with gusty winds presenting possible challengers for boaters. Dense fog is also expected in Santa Barbara and San Luis Obispo counties.

The National Weather Service is urging Californians to stay up to date with the latest weather conditions by checking local forecasts or visiting the NWS Los Angeles website . Those with questions or weather reports can call 805-988-6626.
