Summary

Newsom Declares Emergency

Governor Gavin Newsom declared a state of emergency in California ahead of the Kelvin wave.
NOAA reported the Kelvin wave could lift West Coast sea levels by six inches to a foot within weeks.
Scientists said warm water in the wave is up to 13.5 °F hotter than typical Pacific temperatures.
Sea surface heights rose up to half a metre in parts of the eastern Pacific by September 20 2026.

Summary

Cage Sinkhole Collapse

Actor Nicolas Cage's Malibu beachfront driveway collapsed into a sinkhole, rupturing a gas line and prompting evacuations.
Marin County’s chief resilience officer said rising sea levels forced reassessment of flood-risk baselines and sandbag distribution plans.
Caltrans deployed road-closure and snow-removal equipment along vulnerable coastal highways ahead of the Kelvin wave.
California National Guard prepared flood-response teams and search-and-rescue units for potential coastal inundation.

Summary

Scientists Warn Flood

The Kelvin wave brings subsurface temperatures 7.5 °C above average, matching the 1997 event.
It travels about 25,000 km beneath the Pacific over roughly 120 days at ~6 mph.
Scientists warn the wave could combine with winter storms, raising water levels up to 14 inches.
A five-centimetre baseline sea-level rise doubles the probability of coastal flooding, per risk assessments.
The 1997-1998 super El Niño caused about $96 billion in global losses, underscoring economic stakes.

History

Historical Context

During 1997 the El Niño that peaked in 1998 produced record Pacific warming, while NASA launched the Tropical Rainfall Measuring Mission in November, beginning satellite monitoring of extreme precipitation. That same year the Central European flood swept Poland, Germany and the Czech Republic, and a $37 billion WorldCom-MCI merger highlighted the era’s economic scale, framing today’s heightened flood-risk planning in California.
