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.

Hawaii Braces for Fresh Downpour as Storms Prompt Flood Risks

Another tropical storm is forecast to drench Hawaii with 3–15 inches of rain through Friday, triggering a statewide flood watch as soils saturated by March’s deluge raise the risk of flooding and landslides; Kauai is expected to take the heaviest hit first, followed by Oahu, Maui and the Big Island, with gusts over 60 mph and moisture lingering into the weekend after March’s record rain caused evacuations and more than a billion dollars in damage.

Kona storm returns to Hawaii, renewing flood threat across the islands

A potent Kona storm is bringing heavy rain to Hawaii, renewing flood fears two weeks after the state suffered its worst flooding in 20 years. Forecasters expect about 4–8 inches of rain statewide, with heavier bands over 10 inches possible, threatening Oahu, the Big Island, and Kauai. A flood watch remains through Friday, and Honolulu will activate its Emergency Operations Center with first responders deployed to vulnerable areas, as evacuations may become necessary. This marks the third Kona storm to hit Hawaii since mid-March, following March floods that dumped a foot of rain on Oahu and caused hundreds of rescues; some locations recorded up to 25 inches in a 24-hour period.

Hawaii storms cause $1B in damage, hundreds rescued as floods surge

Two back-to-back storms drenched Hawaii with up to 50 inches of rain, driving about $1 billion in damages and prompting hundreds of rescues and mass evacuations across Oahu and Maui; officials say the flooding is the worst since 2004, with ongoing road closures, dam monitoring by the National Guard at Wahiawa, and advisories to avoid driving through deep water, while the White House has offered support and there have been no reported fatalities so far.

Hawaii on high alert as worst flooding in two decades prompts mass evacuations

A Kona Low storm dumped extreme rainfall across Oahu and Maui, triggering a statewide flood watch and mass evacuations—more than 230 people rescued and thousands displaced—as authorities warn that saturated ground means even less rain could trigger dangerous floods; a dam near Honolulu is at risk of collapse, and damages could exceed $1 billion, marking Hawaii’s worst flood in 20 years.

Hawaiʻi’s Rain Record Run: Kona Lows Drench the Islands in Historic Downpours

Death Valley bursts into a decade’s most dramatic bloom after wet winter

A rare, expansive wildflower bloom has transformed Death Valley National Park after above-average fall and winter rainfall, marking the most extensive bloom in ten years. Blooms are visible at low elevations along Badwater Road with higher-elevation blossoms expected later, and visitors are urged to stay on trails to protect the fragile desert habitat.

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.

Rainy-season surge puts Sydney beaches in shark spotlight

Rainy-season surge puts Sydney beaches in shark spotlight

A spate of four shark bites in 48 hours along eastern Australia—three near Sydney and a fatality in Sydney Harbour—has been linked to heavy rains that flushed freshwater into coastal waters, drawing bull sharks and baitfish. Experts say the incidents reflect environmental and reporting factors rather than increased aggression, discourage culls, and stress practical safety measures like avoiding swimming after rain and staying aware of beach warnings.
