Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sun Oct 15 2017

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

The National Hurricane Center is issuing advisories on Hurricane
Ophelia, located over the eastern Atlantic Ocean more than 300 miles
east of the easternmost Azores.

1. A broad trough of low pressure centered over the Virgin Islands and
the northern Leeward Islands is producing disorganized showers and
squalls over portions of the Leeward Islands and adjacent Atlantic
waters. This activity is expected to spread across the Virgin
Islands and Puerto Rico later this morning and continue into the
afternoon. Upper-level winds are forecast to remain hostile for any
significant development to occur during the next day or two.
However, the environment could become somewhat more conducive for
development by early next week when the system begins to move
northward and then recurves over the west-central Atlantic Ocean.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...50 percent.

Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sun Oct 15 2017

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

The National Hurricane Center is issuing advisories on Hurricane
Ophelia, located over the far eastern Atlantic Ocean a few hundred
miles south-southwest of Ireland.

1. A large area of showers and thunderstorms located over the
southwestern Atlantic Ocean between Puerto Rico and Bermuda is
associated with a broad area of low pressure, which is centered
about 150 miles east-northeast of the Turks and Caicos Islands.
Any development of this low while it moves generally northward over
the western Atlantic during the next day or so is expected to be
slow to occur due to strong upper-level winds, and the system is
likely to merge with a front and become extratropical in a couple of
days.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 5 days...medium...40 percent.

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

1. Broad low pressure centered about 500 miles southwest of Bermuda
continues to produce an elongated area of disorganized showers and
thunderstorms which extends from Puerto Rico northward over the
western Atlantic Ocean.  The low's circulation is not well defined,
and significant tropical development appears unlikely during the
next day or so due to strong upper-level winds.  The disturbance is
forecast to move generally northeastward, merging with a frontal
system over the western Atlantic by Tuesday night.

* Formation chance through 5 days...low...30 percent.
