Hurricane Shary speeds away while Hurricane Tomas organizes

Posted by Sheena Parveen under Daily updates

Hurricane Shary is quickly moving off into the cooler Atlantic waters at a speed of 35mph.  This system poses no threat to the U.S. and will dissipate soon.  It’s hard to see where the weak hurricane is, since it is getting caught up in a cold front.

The track keeps it moving NE along with the front, and soon it will dissipate as conditions deteriorate.

As for Tomas, it is now a category 1 hurricane.  It’s continuing to be organized with more thunderstorm activity near the center today, increasing the wind speeds to 75 mph.  Outflow bands from the storm are apparent, and that indicates low wind shear which will continue over the next several days, possibly strengthening this system to a major hurricane.  Parts of the Lesser Antilles are experiencing hurricane force winds now, along with heavy rain.

Tomas will continue West/NW into the Caribbean Sea, where it has the potential to grow into a very large and strong hurricane.

By the time Tomas near Jamaica, a cold front will exit the Southeast U.S.  This front will act as a wall, not allowing Tomas to move closer to the SE coast.  The storm at that time will either turn South or NE.  The computer models below agree on this cold front interaction, but they are not all agreeing on what direction Tomas will take once it encounters this front.

The GFS model turns Tomas into a major hurricane by next week in the Caribbean Sea, then turns it to the NE with the approach of the cold front.
