A "perfect storm" of El Niño season rain and unusually high King Tides on Christmas Eve could cause some serious snags in holiday travel, especially out of SFO. As the Business Times is reporting, the double-whammy of rain all day on Thursday and an unusually high tide could result in some surprise flooding of low-lying roads, including in and around SFO.
The high tide on Thursday morning is expected to peak between 9 and 10 a.m., and will top 6.8 feet a high tide that is likely to cause the common flooding of roadways in Marin County like around Sausalito, possibly affecting Highway 101 near Tiburon as well.
According to Weather Underground, only about one-tenth of an inch of rain is expected Thursday in SF, much of it falling between 6 a.m. and noon, but this will affect travel as well. Look for the Embarcadero and that area of Cesar Chavez near the 280 on-ramp that always floods to potentially be impacted as well.
SFO keeps a running tote-board of flight times and delays here, so if you're planning to travel on Thursday, one of the heaviest travel days of the year, keep a close eye on that in the early a.m.
