California Braces for a Potentially Record-Setting El Niño Winter

California Braces for a Potentially Record-Setting El Niño Winter

Forecasters warn a potentially historic super El Niño could develop by fall, with NOAA predicting a >90% chance of El Niño and up to a 50% chance it will be strong; if it arrives, Southern California could see a wetter winter that replenishes water supplies but raises the risk of floods, debris flows and coastal erosion, even as it may reduce wildfire risk. Forecasters caution that even strong El Niños don’t always deliver predictable weather, citing past events (1982-83, 1997-98) that varied widely in rainfall. The pattern is tied to warmer Pacific waters and altered jet streams, and climate change could be intensifying swings; impacts may extend to marine life as warmer seas affect plankton and sea lion rookeries along the Channel Islands. More clarity is expected between May and June as models improve.

SoCal’s March heat wave ends as weekend cooldown arrives

SoCal’s March heat wave ends as weekend cooldown arrives

Southern California’s record-breaking March heat wave is easing this weekend, with coastal highs in the mid-70s to low-80s and inland in the 90s after a stretch that saw 102°F in Woodland Hills and 93°F in Lancaster. The National Weather Service warned that heat advisories should expire by Friday night, though next week is expected to stay hot overall. Officials caution about heat-related illness, especially for those without AC, as the unusual warmth continues to influence the region.

SoCal March Heat Wave Smashes Records, Feels More Summer Than Spring

SoCal March Heat Wave Smashes Records, Feels More Summer Than Spring

Southern California and the Southwest are in the grip of a record-breaking heat wave through the week, with high temps in the 90s to around 110 degrees, including North Shore’s 108-degree day tying a national March record and a nearby Arizona town hitting 110. Extreme heat warnings continue into Friday as officials urge precautions against heat illness, and some residents faced daylong power outages. Forecasters expect a modest cool-down this weekend as high pressure eases, followed by a rebound next week; meanwhile dry grasses from a wet winter raise wildfire concerns, and snowmelt could strain reservoirs if the pattern stays dry.

SoCal braces for historic March heat as records fall

Southern California is entering a multi-day heat wave that has already set daily records in the LA area (Hollywood Burbank Airport 92°, Pierce College 97°) and is forecast to push into the 90s–100s inland through Friday, with coastal areas heating rapidly; forecasters warn of dangerous heat illness and advise cooling centers, hydration, and checking on vulnerable neighbors.

SoCal Braces for Potentially Record-Breaking March Heat Wave

A dangerous, multi-day heat wave is forecast for Southern California and much of the U.S. Southwest next week, with highs near 100°F or more (Downtown Los Angeles around 101°F). The National Weather Service has issued an extreme heat watch and a Monday heat advisory as temperatures rise 25–35 degrees above normal. The heat threatens babies, young children, and the elderly, prompting Mayor Bass to urge cooling centers at city facilities; residents should stay indoors, hydrate, and limit sun exposure to early morning or evening hours. While wildfire fuels are currently moist, the dry heat could accelerate drying with no significant rain in sight. Downtown L.A. could approach its 1879 March record of 99°F, potentially breaking it.

SoCal Braces for Back-to-Back Heat Records as LA Sees 90s to 100s

SoCal Braces for Back-to-Back Heat Records as LA Sees 90s to 100s

A multi-day heat wave hits Southern California with LA-area temperatures expected in the 90s (and inland near 100), likely tying or breaking more than a dozen local records. A coast-wide heat advisory (10 a.m.–8 p.m.) runs through Friday as officials warn of heat-related illness and urge precautions. Weak onshore winds mean slow cooling along the coast, with 95-degree highs in Pasadena, San Gabriel and Burbank and 94 in Long Beach; Santa Monica Pier may reach 85. Beach warnings due to high bacteria levels persist, and officials caution against heat exposure, especially for vulnerable groups. A second hot spell is forecast for early next week, potentially surpassing monthly records, while the risk of fires remains possible but not widespread thanks to recent rainfall.

SoCal braces for record heat as temps hit 90s and beyond

Southern California is bracing for a dangerous heat wave with highs in the 90s and some triple-digit readings, prompting health warnings about heat illness and signaling a potentially earlier start to fire season. While not triggering red-flag fires yet, the prolonged heat—20–30 degrees above normal—could quicken drying and increase grass fires; cooling centers will be opened and residents without AC urged to seek relief, with a cooldown then another heat spike expected next week.

SoCal gas prices surge past $5 as Iran conflict drives costs higher

Gas prices climbed across Southern California as the Iran conflict pushed crude costs higher. California’s average topped $5 per gallon with Los Angeles County about $5.17; some stations hit $8+ while others remained around $4. Analysts point to state policies and lower in-state production as contributing factors, with AAA noting a national price rise.

Ventura County coastline cited as SoCal’s fastest-growing beach in new study

Ventura County coastline cited as SoCal’s fastest-growing beach in new study

A Nature Communications study using satellite data from 1984–2024 finds Ventura County’s coast was Southern California’s fastest-growing beach, adding about 500 acres overall though sand accumulation created erosion elsewhere (e.g., near Mugu Lagoon). Growth is tied to downstream sediment from rivers and influenced by coastal structures that block sand flow; dredging helps but isn’t always effective at vulnerable spots. Future beach extent will depend on sea‑level rise and ongoing coastal development along the shore.

SoCal Braces for Heavy Rain, Flooding and 10-Foot Waves

A strong storm is forecast to bring heavy rain, possible flooding and dangerous waves to Southern California from Sunday through early next week, with 1–2 inches of rain in valleys and coast (more in the mountains), potential debris flows in burn-scar areas, gusty winds, and high surf with waves over 10 feet; Bay Area beach hazards are also expected as the system moves through, with mountain snow possible as totals rise.

SoCal cooks under midwinter heat as ridge holds on through Super Bowl week

A midwinter heat wave grips much of California as a persistent high-pressure ridge stretches from the San Francisco Bay Area to Alaska, pushing temperatures about 15–20 degrees above normal through the week and likely into Super Bowl Sunday. Inland areas could reach near 90 F, the Bay Area mid-to-upper 80s, with Santa Ana winds gusting up to 50 mph in the mountains. Light rain and cooler air may appear next week, while overall wildfire risk remains low thanks to lingering moisture, though small fires are still possible.
