Area forecast discussion, Jan 26, 6:36 PM CST, 8 hours 44 minutes before
Area Forecast Discussion
National Weather Service San Juan PR
836 PM AST Fri Jan 26 2018
.UPDATE...SJU doppler radar shows scattered showers over the
north Atlantic and portions of northern, and southern Puerto Rico
these showers will continue through the overnight hours. Strong
east to northeast winds of 20 to 25 mph with higher gusts will
bring low level moisture periodically across the region through
Monday. A strong northerly swell will cause marine conditions to
deteriorate tonight through the weekend across the Atlantic and
local water ways.
&&
.AVIATION...VFR conditions should prevail through the reminder of
the 27/00Z TAF period. Brief -SHRA are possible through 27/12Z due
to strong and fast trade winds bring low level moisture across
the region. At the sfc east to northeast winds of 20 to 25 kts
with higher gusts possible. East to northeast winds of 15 to 20
kts extends from the sfc to 15kft but the winds turn westerly at
25kft to 40kft with winds ranging from 15 to 40 kts. Some SHRA may
cause terminals to briefly fall to MVFR but MVFR conditions
shouldn't last long.
&&
.MARINE...MARINE...Small craft advisories are in effect across all coastal
waters except across the nearshore waters of southwestern Puerto
Rico. Building seas up to 10 feet and winds up to 25 to 30 knots
are expected. Fresh to strong trades in combination with a large
northerly swell will generate dangerous seas through early next
week. As a result large breaking waves will produce life
threatening rip currents, coastal erosion and coastal flooding
into the upcoming work-week.
&&
.PREV DISCUSSION... /issued 412 PM AST Fri Jan 26 2018/
SYNOPSIS...Shearline will continue to dig southeastward towards
the local area tonight into Saturday. Strong surface high pressure
will build behind the shearline, producing breeze to windy
conditions across the local area through at least Monday.
SHORT TERM...Variably cloudy skies prevailed across Puerto Rico
and the U.S. Virgin Islands this afternoon. Areas of cloudiness
with showers embedded in the trade winds affected the local
islands from time to time. Rainfall accumulation were less than an
inch. This weather pattern will continue through tonight. A
shearline is expected to move across Puerto Rico Saturday and
Sunday, bringing with it an increase in cloudiness, with scattered
to numerous showers both days. Breeze to windy conditions are
expected as a strong high pressure system builds behind the
shearline.
LONG TERM...(from previous discussion) Monday through Saturday
A ridge pattern aloft will hold much of the upcoming week as well
as the following week. At lower levels, a high pressure across
the central Atlantic will promote moderate to strong east
northeast winds Monday through early Tuesday. However by mid week,
the surface high is expected to erode as a frontal boundary moves
over the western Atlantic and closer to the local area. A
seasonal weather pattern is expected to prevail through the
forecast period with trade wind showers at times particularly on
Monday and early Friday. The driest day at this time could be
Wednesday.
AVIATION...SHRA/-SHRA are expected to continue at TJSJ/TIST/TJPS/TISX/TJBQ
and TNCM/TKPK with SCT-BKN lyrs btwn FL020-FL090 ovr local flying
area and en route between islands. SHRA are fcst to develop over
TJMZ btwn 26/18z-23z. The winds will continue from the E-NE at 15
to 25 knots with higher gusts in/near SHRA. Breezy to windy
conditions are forecast to persist through the weekend.
MARINE...Small craft advisories are in effect across all coastal
waters except across the nearshore waters of southwestern Puerto
Rico. Building seas of 5 to 7 feet and winds up to 25 to 30 knots
are expected. Fresh to strong trades in combination with a large
northerly swell will generate dangerous confuse seas through early
next week. As a result large breaking waves will produce life
threatening rip currents, coastal erosion and coastal flooding
into the upcoming work-week.
