Area Forecast Discussion
National Weather Service SAN JUAN PR
Issued by National Weather Service MIAMI FL
805 AM AST THU JUN 2 2016
.AVIATION...
The combination of deep layered moisture and day time heating
today will lead to widespread showers across Puerto Rico and the
U.S. Virgin Islands this morning and through the day. Thunderstorm
activity should be mainly limited to Puerto Rico around the 17-18z
time frame. With shower activity there could be brief MVFR conditions.
With the occurrence of thunderstorms brief periods of near IFR to
IFR conditions can be expected and will amend as conditions
warrant. /60 BD

.PREV DISCUSSION... /issued Issued by National Weather Service MIAMI FL/
SYNOPSIS...
Ridge aloft will intensify, as a mid to upper level trough
across the western Atlantic and central Caribbean continues to weaken.
East southeast winds are expected to prevail across the local islands
through Friday as a surface high pressure holds across the central Atlantic.
Another round of showers and thunderstorms are expected this afternoon
with a somewhat drier weather pattern and hazy skies expected to prevail
Friday and the upcoming weekend.
DISCUSSION...
Partly cloudy skies prevailed across the local islands overnight
and early this morning with a few passing showers observed across
the USVI and the east coastal areas of Puerto Rico. Coastal
temperatures were in the mid to upper 70s and winds were east
southeast at 10 mph or less. As the upper level ridge intensifies
across the forecast area, the intensity and areal coverage of
afternoon showers and thunderstorms will decrease. However shower
and thunderstorm development still expected over and north of the
Cordillera Central this afternoon due to enough moisture, diurnal
heating and local effects. Due to already saturated soils...urban
and small stream flooding is also possible. As the ridge holds
across the eastern Caribbean Friday and into the upcoming weekend,
low level moisture will erode across the forecast area. This will
result in a generally fair and mainly stable weather pattern with
a few locally induced showers and thunderstorms across the western
interior of Puerto Rico each afternoon. Hazy skies are also
expected as SAL reaches the eastern Caribbean. Low level moisture
will increase across the local area early next week as a mid to
upper level trough develops across the tropical Atlantic and into
the eastern Caribbean.
AVIATION...
VFR conds expected through 02/15Z across the local terminals.
SHRA/TSRA development expected thereafter, likely causing VCSH/VCTS
at TJSJ, TJBQ, and TJMZ with possible MVFR conds at TJBQ between
02/17Z and 02/20Z in possible TSRA. Increasing clouds through the
day will also cause MTN obscurations. SFC winds from the ESE to SE
at around 5-10kt until 02/12Z, increasing to 10-15kt and gusty near
SHRA/TSRA after 02/12Z.
MARINE...
Fresh winds across the regional waters will keep the seas
around 4-7 feet over the next few days. As a result...a Small Craft
Advisory is in effect for the Offshore Atlantic Waters through
Friday.
