Area Forecast Discussion
National Weather Service San Juan PR
115 PM AST Mon Jul 9 2018
.UPDATE...
Thunderstorms with torrential rainfall and frequent gusts have

associated with the remnants of Beryl, which is a strong tropical
wave. No changes were made to the inherited forecast and this
activity.
&&
.AVIATION...
SHRA/TSRA will continue to move over PR and on occasion affect
the USVI during the rest of the day. SHRA/TSRA continues to
develop across the waters which are expected to continue to affect
most TAF sites in PR this afternoon. MVFR ceilings and
occasionally MVFR visibilities are expected to continue during the
day. Winds associated with the disturbance will be 10-20 kts with
gusts around 30 to 40 knots through at least 10/0100. MNT obsc is
expected through late tonight over the mountains of PR.

.PREV DISCUSSION... /issued 440 AM AST Mon Jul 9 2018/
SYNOPSIS...A vigorous tropical wave associated with the remnants
of Beryl will move across the U.S. Virgin Islands and Puerto Rico
today...bringing heavy rainfall, strong gusty winds and rough
seas. The effects of this tropical wave will last until late
tonight. Dry and stable air will spread over the Northeast
Caribbean region during the overnight hours and Tuesday. Saharan
dust particles will reduce somewhat the visibilities and limit
the development of showers the rest of the work week.
SHORT TERM...Today through Wednesday...
Weather conditions will continue to deteriorate as the remnants
of Beryl crosses the local region. These remnants are moving
quickly across the Eastern Caribbean around 25 MPH. As a result...
several rounds of showers will affect the local islands through
tonight. The main hazards will be torrential rainfall and strong
gusty winds. Winds will peak at 20-25 MPH with strong gusty
winds of 35-45 mph. Rainfall accumulations could range between
2-4 inches with locally higher amounts in some spots due to the
interaction with orography. Therefore, urban flooding and rapid
rises along rivers and small streams, as well as mudslides in
areas of steep terrain are also likely across portions of the
islands today.
Weather conditions will significantly improve on Tuesday as a dry
and more stable air mass reaches the northeast Caribbean region.
However, hazy skies will reduce visibilities and deteriorate the
air quality over the islands through midweek. Although, an upper
level trough/TUTT will approach from the east, the local area will
remain in the stable side of the TUTT. This will keep the mid-
level dry/stable and a strong trade wind cap the second part of
the week.
LONG TERM...Thursday through Tuesday...
A more seasonal pattern is expected through much of the long term
period with a TUTT low moving westward towards the northern Leeward
Islands and then meandering north of the forecast area this weekend.
At the surface, 1028 to 1032 mb high pressure will persist over the
north-central Atlantic, maintaining moderate easterly winds through
next week. Rain chances increase Friday and Saturday with a slight
increase in moisture moving across the region. Showers and
thunderstorms are expected each afternoon, but coverage won't be
widespread, as moisture is kept mainly below 700 mb with some mid-
level dry air spreading across the area. Under easterly winds,
temperatures should be near normal with hazy skies returning by
mid-week as another swath Saharan dust reach the eastern
Caribbean.
AVIATION...Deep tropical moisture from the remnants of Beryl
will continue to approach the USVI and Puerto Rico from the
southeast later this morning and through most of the day. Infrared
satellite imagery shows cloud top cooling to -70 to -75C in the
northern Leeward Islands with scattered to numerous showers and
thunderstorms from TKPK to TNCM. Lowered visibilities and ceilings
will improve as the remnants of Beryl continue northwestward
towards Puerto Rico. MVFR ceilings and occasionally MVFR
visibilities are expected during the day across Puerto Rico. Winds
associated with the disturbance will also be strong at times with
localized gusts approaching 35 to 40 knots at times in heavier
convection. Conditions should improve tonight across the forecast
area with diminishing winds and rising ceilings.
MARINE...Marine conditions will continue to deteriorate as the
remnants of Beryl moves across the local waters today. Wave heights
of 8 to 10 feet are expected with sustained winds of 20 to 25 knots
with gusts to around 40 knots, maybe even slightly higher at times.
There is a high risk of rip currents and a high surf advisory. Winds
and seas will gradually improve late Tuesday. Please see our marine
products for more details.
HYDROLOGY...Rainfall rates of 2-3 inches per hour could trigger
flooding of small streams and rivers as well as mud slides in
areas of steep terrain. Residents living along streams, rivers and
creeks are urged to remain vigilant as weather can change quickly.
