Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Mon Oct 14 2016

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

The National Hurricane Center is issuing advisories on newly formed
Tropical Depression Eleven, located in the central Gulf of Mexico,
and on Post-Tropical Cyclone Julia, located just offshore of Cape
Cod, Massachusetts.

The National Hurricane Center is issuing advisories on Potential
Tropical Cyclone Twelve, located about 100 miles south of San Juan,
Puerto Rico.
* Formation chance through 48 hours...high...70 percent
* Formation chance through 5 days...high...90 percent

A broad area of low pressure located a couple of hundred miles
south-southwest of Jamaica is accompanied by showers and
thunderstorms.  This disturbance remains disorganized, and
development, if any, should be slow to occur over the next couple
of days while it moves slowly northwestward.  Environmental
conditions are expected to be marginally conducive for some
development when the system moves over the northwestern Caribbean
Sea and the southern Gulf of Mexico later this week.  Locally heavy
rainfall is possible over portions of Haiti and Jamaica today, and
will likely spread across the Cayman Islands and eastern Cuba on
Tuesday.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...30 percent

A westward-moving tropical wave is producing showers and
thunderstorms across the Windward Islands.  However, upper-level
winds are becoming unfavorable for further development of this
system.
* Formation chance through 48 hours...low...10 percent
* Formation chance through 5 days...low...10 percent

A non-tropical area of low pressure could develop over the next
couple of days a few hundred miles east of Bermuda, and this low
will have some potential to gradually acquire tropical
characteristics as it moves slowly southward.
* Formation chance through 48 hours...low...near 0 percent
* Formation chance through 5 days...low...20 percent

Public Advisories on Tropical Depression Eleven are issued under WMO
header WTNT31 KNHC and under AWIPS header MIATCPNT1.

Special Tropical Weather Outlook
NWS National Hurricane Center Miami FL
400 PM EDT Thu Aug 21 2014

Updated for reconnaissance information

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

1. Data from an Air Force Reserve Hurricane Hunter aircraft indicate
that the circulation associated with the small low pressure area
approaching the Leeward Islands is poorly defined.  In addition, the
associated shower activity has decreased during the past few hours.
The aircraft did, however, find a small area of tropical-storm-force
winds on the northeast side of the low.  Environmental conditions
are expected to be conducive for some development during the next
day or so, and a tropical depression or tropical storm could still
form while the system moves west-northwestward at around 20 mph
across the Lesser Antilles. The mountainous terrain of Hispaniola
could limit development during the first part of the weekend, but
conditions are expected to become more conducive for development by
Sunday when the system is forecast to move near or over the Bahamas.
Regardless of tropical cyclone formation, gusty winds and heavy
rainfall are expected across portions of the Lesser Antilles, Puerto
Rico, and the Virgin Islands through Friday, and over Hispaniola
late Friday and Saturday. Interests in those islands and in the
Bahamas should closely monitor the progress of this disturbance. An
Air Force Reserve Hurricane Hunter aircraft is scheduled to
investigate this system again tomorrow afternoon.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...high...70 percent.
