Area Forecast Discussion
National Weather Service San Juan PR
Issued by National Weather Service MIAMI FL
802 AM AST Fri Sep 22 2017

.AVIATION...
Persistent, moist south to southeast flow will continue to favor
showers and scattered thunderstorms today over Puerto Rico along
with considerable mid to high level clouds. Highest chance for
rain will be in the high terrain and upslope regime over southern
Puerto Rico. Across the Virgin Islands and Lesser Antilles, a
slightly drier air mass moving in with prevailing VFR outside of
the typical scattered showers.

.PREV DISCUSSION... /Issued by National Weather Service MIAMI FL/

SHORT TERM...It is difficult to ascertain conditions in the
area as nearly all communications links are down. However, some
gages continue to report. Stream levels are falling over the north
and west side of Puerto Rico, but rising in the east. Flooding
continues with the worst of it in far west Puerto Rico and along
the north coast west of San Juan.

Hurricane Maria has moved out of the area, but persistent south
to southeast flow along with precipitable water values around 2.3
inches will continue into Tuesday. Thus, precipitation is expected
to continue over the south portion of the islands, especially on
Puerto Rico, but nothing like what Maria brought.

Any additional rain that Puerto Rico receives, which is hard to
detect with the TJUA radar down, will aggravate the ongoing record
flooding on many of the rivers, and there is plenty of water away
from the rivers as well. Mudslides have occurred and will likely
continue. Thus, will keep the Flash Flood Watch up across all of
Puerto Rico and the US Virgin Islands.

Heat Index values will be in the mid to upper 90s Friday but will
rise to around 100 or more by the weekend. This will make
recovery efforts difficult and overall living unpleasant as
electricity remains out across the island.

LONG TERM...The pattern will change Tuesday into Tuesday night.
Flow will become easterly and precipitable water values will drop
to around 1.75 inches. This will bring drier conditions to all
but possibly the northeast portion of the island.

MARINE...Small Craft Advisories remain in effect over the area,
mainly for hazardous seas, but south to southeast winds will
remain significant as they are not the usual wind direction.
Showers and thunderstorms with heavy rain, locally higher winds
and waves, and reduced visibilities will be possible in the outer
bands of Maria through the weekend. Seas will subside with time,
and the more typical trade winds will return Tuesday night.
