NATIONAL HURRICANE CENTER:

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
130 PM EDT Tue Apr 18 2017

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

A non-tropical low pressure system is located over the central
Atlantic about midway between Bermuda and the Azores Islands. This
low is producing disorganized cloudiness and showers, and an area of
gusty winds to the west of the center. This system has the
opportunity to become a subtropical cyclone over the next 24 hours
before it becomes absorbed by a larger extratropical cyclone. The
next Special Tropical Weather Outlook will be issued by 2 PM EDT
Wednesday.  For additional information on this system, please
see High Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...low...30 percent
* Formation chance through 5 days...low...30 percent

High Seas Forecasts issued by the National Weather Service can be
found under AWIPS header NFDHSFAT1, WMO header FZNT01 KWBC, and on
the Web at http://www.opc.ncep.noaa.gov/shtml/NFDHSFAT1.shtml.

I have noticed more convection (thunderstorms) near the center of circulation.  This system could become a sub-tropical system before merging with an extra-tropical system.  Only a threat to shipping!

STORM INVESTIGATION 91L OUT OVER THE NORTH CENTRAL ATLANTIC.

 NATIONAL HURRICANE CENTER IS MONITORING A WELL FORMED GALE CENTER OVER THE NORTH CENTRAL ATLANTIC FOR SUB-TROPICAL DEVELOPMENT.  THIS SYSTEM HAS A 30% CHANCE FOR DEVELOPMENT DURING THE NEXT 48 HOURS AND DURING THE NEXT 5 DAYS.  THIS GALE CENTER IS ONLY A THREAT TO THE SHIPPING LANES.

RTW

A non-tropical low pressure system located over the central Atlantic
about midway between Bermuda and the Azores Islands is producing an
area of gale-force winds to the west of the center.  This low is
currently producing only limited shower activity, but environmental
conditions could favor additional development and this system has
some potential to become a subtropical cyclone over the next day or
so as it moves generally eastward.  The next Special Tropical
Weather Outlook will be issued by 2 PM EDT Tuesday.  For additional
information on this system, please see High Seas Forecasts issued by
the National Weather Service.
* Formation chance through 48 hours...low...30 percent
