Area Forecast Discussion National Weather Service San Juan PR 327 PM AST Mon Mar 1 2021

SYNOPSIS.

Calm weather is expected for the next few days given dominant high pressure and plenty of dry air across the region. Passing showers will be possible, primarily impacting eastern Puerto Rico. Winds have slowed down just a bit today, but will remain at or above average for the next few days due to high surface pressure to our north. More moisture moves in for the weekend from the south that will give us a better chance for shower activity. Seas will remain hazardous into tomorrow.

SHORT TERM. Rest of Today through Wednesday .

Fairly uneventful weather conditions are expected in the short term due to high pressure and stable conditions over the region. Mid to upper level high pressure is currently building over the region, and its effects will last the full duration of the short term period. Dry and warm air at mid-levels, with an inversion around 700 mb, will keep showers fairly weak and unimpactful. Near the surface, high pressure to our north will keep the easterly trade winds brisk, but a bit weaker during the next few days compared to the last few days.

Below normal moisture content will be with us through tomorrow under east-northeasterly winds. Thus, a few passing showers are possible overnight tonight and tomorrow morning for north and east Puerto Rico. During the day, isolated showers are possible across the region, but only light showers are expected. Overnight Tuesday into Wednesday, some patches of weak moisture are expected to move in as our winds turn more easterly and then east-southeast later during the daytime. Thus overnight, isolated to scattered showers are possible for eastern Puerto Rico and the USVI. Even with these patches of moisture for Wednesday, the moisture is so minimal that only isolated showers are likely, with maybe a few areas of scattered showers over eastern Puerto Rico in the morning and northwest Puerto Rico the afternoon. Brisk low-level steering flow winds will keep all showers moving along fairly quickly to thus limit their impact.

LONG TERM. Thursday through Tuesday .

PREV DISCUSSION. /issued 501 AM AST Mon Mar 1 2021/

A mid-level ridge will dominate the local weather conditions through the end of the workweek. This will promote stable conditions aloft and maintain the trade wind cap across the region. Precipitable water content through this period will be around 1 inch, and diurnally induced afternoon showers should result in minor rainfall accumulations. A surface high pressure will continue to move further away into the central-eastern Atlantic, while a polar trough and associated surface front exits the U.S. East Coast by Friday. The base of the trough and the front are expected at this time to remain just north of the region, however, a pre-frontal trough is expected to develop in a southeasterly wind flow and move over the region on Saturday. Pooling of moisture is expected through the weekend into early next week. Precipitable water content is forecast to increase from 1.75-2.00 inches during this time. Therefore, expect wetter conditions and the potential for urban and small stream flooding will increase due to periods of moderate to locally heavy rainfall. Drier conditions are expected by Tuesday.

AVIATION.

VFR conditions will continue through the period. Mostly clear to partly cloudy skies will also continue, with occasional isolated light SHRA. VCSH most likely for TJSJ overnight and least likely for TJPS and TJMZ. Easterly winds mostly around 15 to 20 knots with gusts up to 30 kts will affect the local terminals. Winds will drop around 10 knots after 01/23z.

MARINE.

Seas are expected to weaken between now and tomorrow as winds also relax a bit across the region. Still, seas will remain around 6 to 10 feet for the Atlantic and 5 to 8 feet for the Caribbean through tonight. For beachgoers, the risk of rip currents continues high for the north-facing beaches of Puerto Rico, the southeast coast of PR, Culebra, the northwestern beaches of St Thomas, and the north and east coast of St Croix.
