Area Forecast Discussion
National Weather Service Key West FL
316 PM EDT Tue Jun 27 2017

The afternoon hours started with isolated showers across the
Florida Keys coastal waters, followed by some clearing of the
skies. Temperatures were from the mid 80s to near 90 degrees
across the islands with winds from light and variable to the
southeast 5 to 10 mph.

A surface high pressure in the Atlantic, will extend westward to
the Bahamas, leaving the Florida Keys in a weak pressure gradient
area. This will allow for winds to be light and variable this
evening. Shower coverage will stay in the isolated to scattered
range tonight and through the next few days. The start of the
weekend will be drier as depicted by the GFS and somewhat by the
European model. I slightly adjusted downward to reflect this. By
tomorrow afternoon, a high pressure will exit the eastern United
States, allowing for the winds to stay from the east to southeast
locally and pick up some speeds. Temperatures will stay within the
range we have experienced during the last week, with no relief in


Light breezes from the southeast will become variable this evening
across most of the Florida Keys coastal waters. However, the
Straits of Florida will experience a shift in the winds as the
Cuban sea breeze allows the winds to increase to near 10 knots
from the northeast. After sunset, winds will return from the east
to southeast. This increase in the winds over the Straits of
Florida south of between Tortugas Ecological South and Marathon
Humps is expected to occur every evening during the next several


Until 12z/28th, VFR conditions should predominate at the Key West
and Marathon terminals. Southeast to south winds of less than 10
knots will become light and variable by late this afternoon.
