Area Forecast Discussion National Weather Service San Juan PR 859 PM AST Sun Mar 7 2021

UPDATE.

Mostly fair weather prevailed over all the forecast area, a few quick passing showers were observed over western sections of Puerto Rico in the late afternoon hours. These weather conditions will continue for the overnight hours. A few passing showers could be possible over eastern coastal sections of Puerto Rico and the U.S. Virgin Islands in the morning hours. However, not significant rainfall accumulations are expected with this activity. A change in wind direction is forecast tomorrow afternoon, more to the northeast. As a result, afternoon shower activity, if any, to southwestern sections of Puerto Rico.

AVIATION. Mainly VFR conditions are expected for all the TAF sites during the next 24 hours. Winds are expected to maintain between VRB to E-NE at 5-13 kts.

MARINE.

Relative tranquil marine conditions are expected with seas up to 5 feet and winds at 15 knots or less over the nearshore waters. In the Atlantic offshore waters choppy marine conditions will continue with seas up to 6 feet. Therefore, small craft should exercise caution. For the beachgoers, there is a moderate risk of rip currents across northern sections of Puerto Rico, all the eastern beaches of Vieques and Culebra, as well eastern tip of St. Croix.

PREV DISCUSSION. /issued 500 PM AST Sun Mar 7 2021/

SYNOPSIS . Fair weather conditions expected tonight and early Monday. Winds turn from the east to northeast during the first part of the week. A weak induced surface trough will increase moisture content early in the week. A northerly swell will cause hazardous seas starting on Tuesday.

SHORT TERM . Today through Tuesday .

A surface high pressure over the central Atlantic and a cold front over the western Atlantic will maintain an east to southeast wind flow through at least tonight across the region. In addition, a mid-level ridge will continue to promote drier above 700 mb tonight. Therefore, fair weather conditions should continue through at least Monday monday morning across the islands. On Monday, a pre-frontal trough is expected to develop mainly north of the area as the cold front moves closer, this will cause winds to turn from the northeast through the short term period. Therefore, less warmer temperatures are expected during the first part of the workweek. Due to the northeasterly steering winds and small surges in low-level moisture, diurnally induced afternoon showers are expected to develop each day over the southwestern quadrant of Puerto Rico. During the night time, a cool advective pattern will promote shower activity across the USVI and over the north and east sections of PR.

LONG TERM . Wednesday through Sunday . /from prev discussion

An old cold front will linger north of the islands, promoting moisture pooling over the region on Wednesday. The frontal boundary will linger off to the north until it dissipated or lifted away from the northeast Caribbean. Behind the front, a surface high-pressure will move eastward across the western Atlantic and will build across the central Atlantic throughout the week. This high-pressure will increase local winds Wednesday and Thursday, diminishing Friday into the weekend.

On the other hand, an amplifying mid to upper-level trough over Cuba/Jamaica will approach PR/USVI weakening the ridge aloft. It will cross the western Caribbean until its axis re-locate near the Hispaniola by the second part of the week. They are some discrepancy between the solutions of GFS and ECMWF. However, they are consistently indicating an unstable weather pattern Thursday through Sunday.

AVIATION . VFR cond thru prd. Mstly isold SHRA ovr regional waters and en route btw islands. Isold-SCT SHRA psbl ovr NW PR and VCTY of TJMZ/TJBQ til 07/22Z but no wx impacts fcst for local terminals at this time. Winds mainly FM SE at 10 to 15 kts with some sea breeze variations and briefly higher gusts . then bcmg calm to light and variable aft 07/22Z.

MARINE . A northerly swell will move across the Atlantic waters and passages on Tuesday. Moderate to fresh northeast trades will also return during the first part of the week, causing choppy conditions across the regional waters. Therefore, hazardous seas are expected during this time and Small Craft Advisories will be in effect due to seas greater than 7 feet. The swell will cause a high risk of rip currents across most of the north facing beaches of the islands from Tuesday through the end of the week.
