Major M8.2 earthquake and Tsunami Warning for Alaska. Severe thunderstorms and the LI forecast:

- An incredibly strong magnitude 8.2 earthquake occurred 56 miles off the southern coast of Alaska with strong aftershocks. A Tsunami Warning is in effect for parts of Alaska. From Dr. Lucy Jones just now: "The M8.2 Alaska quake is on the subduction zone interface. That means the seafloor under the Pacific Ocean is being pushed under the Alaskan peninsula. It also means it generated a tsunami. There is a Tsunami watch for the West Coast. The warning for Hawaii has been cancelled, because the waves are focused east of Hawaii and the event isn't that large. This location is not a surprise. I led a USGS project to model a bad tsunami for Los Angeles and we put the model location at the same place. It is just west of the 1964 quake and historically hadn't had much activity. But our modeled quake was bigger. The main impacts for this M8.2-produced tsunami will likely be strong currents in harbors on the West Coast of the United States. The first wave will arrive during the night hours, but later arrivals could cause strong currents all day."

- Nassau and southwestern Suffolk have been upgraded to the slight risk (yellow zone) for severe thunderstorms later today into tonight. The main threat would be damaging wind gusts and possibly hail, and even a tornado can't be ruled out. It looks like the best chance for the heavy showers and thunderstorms would be between 4 PM and 10 PM for Long Island, but there will likely be some scattered coverage before and after that time period.
