Area Forecast Discussion
National Weather Service San Juan PR
1124 AM AST Fri Mar 31 2017

.UPDATE...Skies became partly cloudy to mostly sunny during the
late morning hours with no shower activity observed or reported
across the local islands. Only a few light showers were noted
well offshore over the Caribbean waters. Drier air will continue
to filter in across the region under the light to moderate northeast
wind flow. Local and diurnal effects may lead to afternoon showers
across parts of the central and west interior as well as in isolated
areas of the San Juan Metro. Later tonight and through the weekend,
winds are to become more southeasterly as the high pressure ridge
shifts farther east into the central Atlantic, and a cold front
enters the west Atlantic. Still looking for a slight increase in
low level moisture convergence across the region mainly on Saturday
as the local winds shift, and moisture remnants of an old frontal
boundary returns to the forecast area. However no significant flood
problems or weather impacts are forecast. No major changes made to
the inherited forecast package at this time.

&&

.MARINE UPDATE...Fading northeasterly swell will affect the Atlantic
waters today. However a larger long period northerly swell will arrive
and spread across the Atlantic waters and local passages by late Saturday
or early Sunday and continue through a least Monday. A fading NE swell
will generate seas between 5 to 6 feet across the offshore Atlantic
water and the Anegada passage during the rest of the day. Elsewhere
seas of 5 feet or less can be expected with winds of 10 to 15 knots.

&&

.PREV DISCUSSION... /issued 513 AM AST Fri Mar 31 2017/

UPDATE...Brief update to include Fire weather section.

FIRE WEATHER...Relative humidity will reach critical values
today. As a result, A fire weather statement (RFD) has been
issued for the southern slopes of Puerto Rico.

PREV DISCUSSION... /issued 456 AM AST Fri Mar 31 2017/

SYNOPSIS...Surface High pressure will continue to dominates the
local region. Patches of low level moisture associated with an old
frontal boundary will affect the region Saturday. Another high
pressure system is expected to build across the western Atlantic
by Tuesday next week.

SHORT TERM...Today through Sunday...

Surface high pressure system to the north of the local area and a
broad high pressure int he upper levels will create a pattern where
locally induced showers will be the main weather making feature over
PR this weekend with isolated to scattered brief showers over the
waters and around the USVI.

For today, high pressure system north of the local area will
dominate the local wind flow and weather pattern. The local wind
will remain today from the ENE, which will maintain a relatively dry
airmass over the area, limiting the shower development but not
completely inhibiting it. The available moisture will combine once
again with daytime heating and local effects to cause the
development of showers across the interior and western sections of
Puerto Rico this afternoon. Some showers could develop near the San
Juan metro as well. There will be also isolated showers around the
USVI and some may even stream off the islands.

For Saturday, the moisture is expected to increase over the local
area and the winds will shift to a more ESE direction, which will
likely cause variably to mostly cloudy skies as the day progresses.
There will also be afternoon convection across the NW quadrant and
North Central portions of PR and the San Juan metro, as well as
passing showers across the USVI through the day. Saturday looks to
be the day with the best chance of rain in the weekend.

Sunday will still have some moisture, enough to have showers develop
across the areas of sea breeze convergence in PR, which will be
across the NW quadrant of PR due to ESE winds. Isolated showers for
the USVI. Because of the ESE winds and the lower moisture and cloud
cover expected compared to Saturday, this Sunday has the chance of
also being rather warm with temps reaching the upper 80s.

LONG TERM...Monday through Saturday...

Although the remnants of an old frontal boundary are expected to
affect the area Monday, relatively dry and stable conditions are
expected to prevail during the long term period. A high pressure
system is forecast to exit the eastern U.S. and will move across
the western Atlantic by Tuesday. As a result, trade winds are
expected to increase somewhat as pressure gradient tightens.
Overall, pleasant weather conditions are expected.

AVIATION...VFR conds expected through the forecast period across the
local terminals. The local winds will be mainly from the ENE at
about 10-15KT with sea breeze variations developing after 31/13Z.
Some SHRA development is expected in the afternoon across various
points in PR, which could cause VCSH across the terminals in PR
mainly after 31/17Z. Winds will decrease after 31/23Z still easterly
for the most part but TJMZ and TJPS may observe light and variable
winds thereafter.

MARINE...Northerly swell will continue to create a high rip
current risk across the north facing beaches of PR, Culebra and
St. Thomas. A larger northerly swell is expected to arrive across
the Atlantic waters and passages on Sunday. Small craft operators
should exercise cautions across the offshore waters and passages
due to 6 ft seas.
