Hermine May Stall Off The Mid-Atlantic Coast & Become a Hurricane Again

Hurricane Hermine made landfall last night in FL and has been tracking through the southeast today as a tropical storm, bringing winds over 40 mph and several inches of rain.

If you would like to receive these updates the moment they are published, please click here to sign up for email updates.

TS warnings are in effect from the coast of GA up through the Delmarva Peninsula. Tropical storm watches are in effect from Delaware up to the CT/RI border, including Long Island and NYC. Please see the image below for the complete list of watches & warnings as issued by the NHC.

Once Hermine exits the coast of NC tomorrow morning, it should be able to strengthen back to a hurricane by Sunday or Monday. The water temperatures off the mid-Atlantic coast are running above average and there is plenty of ocean heat content for the system to strengthen.

The exact track of Hermine beyond Saturday is still little uncertain and therefore, the NHC has a fairly wide cone Sun-Wed. One thing we know for sure is that Hermine will not be able to make a quick escape out to sea as an area of high pressure will build to the north, preventing a path out to sea. There is a possibility that Hermine could make landfall, but at this time the most likely solution is that Hermine will stall just offshore of the mid-Atlantic coast for a few days and eventually begin to weaken or move out to sea Wednesday or Thursday.

12Z EURO model run today shows a closer track towards the coast.

Even if Hermine does not make landfall, the effects could be devastating to some portions of the coast. At minimum, tropical storm force conditions, heavy rain and a storm surge of 3-5’ feet are possible from Long Island down through SE Virginia. We encourage anyone who has Labor Day plans along the coast to make alternate plans. The closer the system tracks towards the coast, the worse the effects will be. To make matters even worse, some guidance is strengthening Hermine into a CAT or CAT 3 hurricane just offshore. Unfortunately, this could be a devastating setup for some portions of the mid-Atlantic coast early next week. All residents and interests in the regions should complete preparations by tomorrow afternoon.

9/1/16 - Hurricane Hermine Hours Away From Landfall In FL

9/2/16 11AM EDT -  We will have a new discussion on Hermine and the possible impacts to the east U.S. coast this afternoon. Thanks for using Hurricane Tracker.

Hurricane Hermine will be making landfall overnight just east of Apalachicola, Florida as an intensifying hurricane. Right now, Winds are at 75 mph, but we expect those to increase as high as 85 mph before landfall around 2-3 am local time. With this system making landfall, it will mark the end to Florida's 10.9 year hurricane drought. There are numerous watches and warnings in effect from Florida all the way to New Jersey as this storm is forecast to impact much of the eastern United States coastline through early next week (see graphics for watches/warnings below). Unfortunately, this will be occurring over a holiday weekend. If you are in the path of the storm, please review the expected impacts below from the National Hurricane Center.

Once the system makes landfall tonight, it will move through southeastern Georgia and through the Carolinas by Saturday. Once the system exits North Carolina, the storm is likely to get trapped by a blocking ridge of high pressure which would prevent a fast escape out to sea. It's not known yet whether the system will make a second landfall along the mid Atlantic or northeastern United States coast, but at minimum, coastal sections can expect coastal flooding and gusty winds. Waters off the mid Atlantic coast are running well above average and may help allow Hermine to  restrengthen into a hurricane early next week. All interests from the Outer Banks of North Carolina through Massachusetts should definitely keep an eye on the system and check in often for the latest updates and forecast.

Beyond this system, we have a wave in the open Atlantic but it only has a 20% chance of development through the next five days. We may see a 1 to 2 week quiet period before activity picks up again. We will notify you of the next possible system.
