Area Forecast Discussion National Weather Service San Juan PR 140 PM AST Wed Dec 11 2019

SYNOPSIS. Showery conditions will continue to prevail across the forecast area through at least the end of the week under trofiness and enough low level moisture. As the trough aloft weakens, a mid level ridge pattern is then expected to establish across the local islands.

SHORT TERM. Tonight through Friday .

Variably cloudy skies prevailed across the local islands throughout the day with passing showers noted over north and east Puerto Rico as well as the US Virgin Islands. Winds were from the east northeast at 15-20 knots with coastal temperatures in the mid 80s at the lower elevations. Rainfall totals associated with these passing showers, however, were minimal.

The short term forecast remains on track. Continue to expect showery conditions with frequent passing showers mainly across north and east Puerto Rico as well as the US Virgin islands through at least Friday. These wet conditions are the result of trofiness at mid and upper levels as well as precipitable water values near 1.60-1.70 inches. Although wet conditions are expected, rainfall totals will range between 1 and 3 inches over northeast Puerto Rico. Isolated thunderstorms cant be ruled out as well.

LONG TERM. Sat thru Thu . /issued 543 AM AST Wed Dec 11 2019/

A fairly wet weather pattern continues into the weekend as moisture gets pulled up from the southeast into our region. For the weekend, Sunday looks to be the wetter of the two days. Under the direction of the forecasted wind flow, southern and eastern Puerto Rico will see the bulk of the shower activity, with a second maximum in rainfall for northwestern Puerto Rico in the afternoon under the convergent windflow around the island. The atmosphere looks to be more stable for the weekend compared to the short term period, so the thunderstorm threat will be minimal. Low level winds are expected to slow down a little bit, but still have decent speed to keep showers moving along. Thus the threat for local flooding should be rather low.

As has been discussed over the past few days, a strong area of high pressure in the Atlantic has been driving stronger than normal easterly trade winds across the region. These winds are expected to subside a bit as this high moves off to the east over the weekend. However, another area of high pressure will move out over the Atlantic for Monday, and this will once again enhance the low level wind flow. This will impact marine conditions once again, and will keep fairly breezy winds in the forecast. Along with that area of high pressure, drier and more stable air is expected to move in for next week. Long range models are even hinting at some Saharan dust that could work in for the middle of next week. Shower activity is of course possible, but these showers will be less prevalent than what we have seen over the past few days.

AVIATION. VFR conds are expected through the forecast period. However, passing SHRA may produce brief MVFR conds at TIST, TISX and TJSJ at times, but VFR conds should prevail most of the time. Some mountain obscuration are also possible in the interior portions of Puerto Rico and near El Yunque. ENE winds of 15-25 kts below FL100. Wind gusts of 30 kts are possible with SHRA as they pass by.

MARINE. Hazardous marine conditions will continue to prevail across the local waters during the next several days with wind- waves between 6 and 8 feet. Dangerous rip currents are expected as well across the north facing beaches of Puerto Rico, Culebra, Saint Croix and the northwest tip of Saint Thomas.
