Anthony Edwards @edwardsanthonyb.bsky.social · 15hSan Francisco anomalies have entered new territory. Averaged across the month, October tides are running 0.9 feet above normal so far. Today is closer to a foot. If these anomalies persist through November and December, tides will be in top 10 territory, even without a storm. 1101

Anthony Edwards @edwardsanthonyb.bsky.social · 17hTypically, early October tides would be far from coastal flood thresholds, but an El Niño-spurred coastally trapped Kelvin wave moving up the West Coast is suppressing cold water from rising to the surface of the ocean. Water also rises as it warms, a phenomenon known as thermal expansion.sfchronicle.comS.F.

Anthony Edwards @edwardsanthonyb.bsky.social · 23hSymmetrical warm-core hurricanes can transition to messier “post-tropical” storms over the Southwest U.S. while retaining their tropical moisture. This process, known as extratropical transition, is most common in September and October during El Niño (Wood et al 2014). 0123

Anthony Edwards @edwardsanthonyb.bsky.social · 23hThe National Hurricane Center on Wednesday morning extended the forecast cone of an ongoing tropical cyclone — Hurricane Rachel — into California. The storm won’t be a hurricane by the time it nears CA this weekend, but it could still present hazards characteristic of a tropical cyclone.sfchronicle.comThe National Hurricane Center just drew a forecast path for Rachel into California. Is the threat legit?Strong winds, large waves and storm surge are possible in Orange and San Diego counties, with heavy rain and flash flooding possible in Los Angeles, Palm Springs, Las Vegas and Phoenix. 16531
Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026Symmetrical warm-core tropical cyclones can transition to asymmetric cold-core storms while retaining tropical moisture, most commonly in September & October during El Niño. Models are converging onto this possibility with Hurricane Rachel. Main hazards: wind + waves = coastal flooding/erosion 0152
Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026Sick of the heat? There’s big changes are in store for California’s weather this weekend.

Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026Generally 1cm surge from a 1hPa drop on sea level pressure is a reasonable rule of thumb.

Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026This isn’t isolated to San Diego. Tidal anomalies are pushing a foot in San Francisco. A dreaded “perfect storm” — a confluence of El Niño, king tides, along with wind, waves and rain — is feared this winter. It could cause widespread disruptive and destructive coastal flooding.sfchronicle.comCalifornia may see dreaded ‘perfect storm’ at terrible time: Thanksgiving and ChristmasKing tides in California will be extremely high during the Thanksgiving and Christmas weeks. A simultaneous storm could wreak havoc on transportation and push the tides to record territory. 24517
Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026If these anomalies persist through winter, San Diego will break a tidal record by a half foot. 1406
Anthony Edwards @edwardsanthonyb.bsky.social · 07/10/2026Bonkers: Sea levels are running 1.2ft above the late-20th century baseline in San Diego as sea surface temperatures are about 7°F warmer than normal. These highly anomalous ocean temperatures and heights will continue through winter along the California coast amid El Niño. #CAwx 421576

Anthony Edwards @edwardsanthonyb.bsky.social · 06/10/2026Through the first five days of October, San Francisco's tides are running more than 10 inches higher than the late-20th century baseline. About 3 inches of this anomaly are because of long-term sea level rise, the rest can be explained by short-term effects, likely El Nino related. 45017
Anthony Edwards @edwardsanthonyb.bsky.social · 05/10/2026The marine layer is keeping San Francisco much cooler today. Official high temperature so far is just 71.

Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026Forecasting San Francisco heat will forever be a challenge. The sea breeze was just a slight bit more pronounced on Sunday, which has kept temps below forecast.

Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026In late September, forecasters feared Hurricane Polo could cause similar damage. Instead, the storm hooked eastward and made landfall in Baja California, sparing the Los Angeles area from significant swell impacts. 030
Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026This week, Southern California is “playing with a similar setup” to Hurricane Marie. That storm sent large, destructive waves northward in early September. Laguna & Newport Beach were hit particularly hard.

Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026For areas with no sea breeze influence (basically anywhere that's not SF and the Eastshore Freeway corridor), it'll be quite hot thru midweek 030
Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026SF heat advisory does end tonight, yes. I do think it could be extended through Monday. The cooling sea breeze is expected to hit earlier tomorrow, which should lower daytime max temps as well as overnight min temps. 130
Anthony Edwards @edwardsanthonyb.bsky.social · 04/10/2026The first eight days of October will be the hottest on record across much of California, according to NWS forecast data. October can certainly get hot along the CA coast, but this heat wave is unusual because it is widespread. There aren't strong Santa Ana or Diablo winds only heating up coast. 58030
