Hermine hit Florida as a hurricane, now a huge concern for northeast US coast

Today's update is a combination of posts.  The first, summarizing Hermine's landfall on Florida, is available on the Capital Weather Gang blog at:

Tropical Storm Hermine is headed up the East Coast after bruising northern Florida

Not included in that post are some interesting and useful graphs pertaining to storm surge.
Unfortunately, Hermine’s peak storm surge coincided with high tide and created a water level that was 4.7 feet above the “highest astronomical tide” and six feet above the average high tide level.

It was the fifth highest water level ever observed in Cedar Key — the highest in 23 years. The only hurricane to generate a higher water level in the past century was Alma in 1966.

The second part of the update on Hermine, which includes significant coastal impacts expected in the northeast U.S. (prolonged period of coastal erosion and flooding), was written by Capital Weather Gang's Jason Samenow:

Hermine to wallop Mid-Atlantic beaches, serious coastal flooding possible

I have a very long regional radar loop of Hermine available HERE ... please be patient, it may take a while to load.

Elsewhere, Gaston is still out there, now as a tropical storm.  It is over the Azores islands, which were also hit by Hurricane Alex in January. Gaston will continue to rapidly decay over cooler water, so this will likely be the last mention of it.

  1. Almost certainly not a significant threat or a huge concern to anyone north of North Carolina. Except perhaps for those maintaining the beaches.
