Synopsis for puerto rico and the uS. Virgin islands waters - . A surface ridge over the north-central atlantic and the remnants of a front will continue to generate fresh to locally strong east- northeasterly winds. The arrival of drier air tomorrow will reduce the amount of passing showers over the weekend. This will bring periods of passing showers and gusty winds across the regional waters. A fading northerly swell and choppy wind- driven seas will continue to promote hazardous conditions to small craft.

Area Forecast Discussion National Weather Service San Juan PR 441 AM AST Fri Apr 12 2024

SYNOPSIS

Breezy conditions and passing showers will continue through Saturday as the remnants of a front continues to cross the region.
Locally induced afternoon showers are expected during the weekend over western PR, and from streamers developing off the USVI/Eastern PR. A mid- to-upper-level trough and higher moisture content are expected to increase shower and thunderstorm activity across the islands from Monday through Wednesday. Hazardous seas and life-threatening rip currents will continue for the next few days.



SHORT TERM
Today through Sunday...

An overnight radar and satellite imagery analysis indicated persistent shower activity affecting the area, with less frequent to no showers across southwestern Puerto Rico. In the last 6 hours, radar estimates indicated the highest rainfall totals, ranging between 0.5 and 1.5 inches along an area stretching from central Toa Baja westward to northern Barceloneta and around El Yunque National Forest. As reported by official sites, overnight minimum temperatures ranged from 65 degrees in higher elevations to 78 degrees across lower elevations. Winds were generally from the east to east-northeast at 10-20 mph with gusts up to 25-30 mph across windward areas, but light to calm and variable elsewhere.

The forecast for the short-term forecast period remains unchanged.
Breezy to windy east-to-east-northeast trade winds, driven by a strengthening high-pressure system over the western-central Atlantic, will continue to affect the area throughout the forecast period, with wind speeds ranging from 15 to 25 mph at daytime, diminishing to 10-20 mph at nighttime. Although a slight weakening of this flow is likely during the weekend, breezy conditions will persist. The prevailing wind flow will maintain an inflow of moisture today, bringing precipitable water to above-seasonal levels to approximately 1.8 inches this afternoon. A drier-than-normal airmass will likely bring precipitable water values below seasonal thresholds of around 1.0-1.2 inches by Sunday morning. However, this will be short-lived, and an even wetter airmass will cause a spike in moisture levels starting Sunday evening, with precipitable values exceeding well above seasonal levels. The leading mid-level ridge will gradually shift west-southwestward and away from the local islands, steered by a mid-to-upper level trough sinking southward across the western Atlantic. This transition should weaken the trade wind inversion and allow moisture to ascend beyond the 700 mbar layer. However, another ridge is forecast to cross the local islands on Saturday, briefly supporting the reinstatement of the trade wind cap.

Passing shower activity, driven by the prevailing flow, will continue to affect most of the forecast area today. As the day progresses, the focus of the showers will shift to central to western Puerto Rico, as well as regions downwind from isolated mountainous areas and the local islands. With conditions becoming more favorable for deep convective development, afternoon showers will likely produce significant rainfall totals of as much as 1.0- 2.0 inches across western Puerto Rico, where urban and small stream flooding is likely. By tonight, the showers' focus will shift again to the local waters and windward areas, producing isolated rainfall amounts of up to half an inch. Temperatures should range from around 85 degrees at daytime to around 65 degrees at nighttime. Breezy to windy conditions, as previously stated, will persist, with a limited to elevated wind hazard risk across coastal areas and the local islands, where unsecured or outdoor items could blow around or be damaged.

Saturday is expected to follow a less showery weather pattern as a drier-than-normal airmass begins to invade the region, followed by an even drier and more stable weather pattern on Sunday morning.
However, as moisture levels rise and conditions become more conducive for deep convective development by Sunday afternoon, expect an increase in shower activity and, thus, higher rainfall totals that could heighten flooding risks. Breezy conditions will persist, posing a limited wind hazard risk.


LONG TERM
Monday through Friday...

On Monday, the surface ridge over the central Atlantic will weaken, and wind speeds will decrease as a front approaches from the northwest. However, it will remain well north of the region.
At the same time, a mid-to-upper-level trough will move from the southwestern Atlantic into the northeastern Caribbean and linger over the area through midweek, providing good divergence aloft and favorable dynamics for thunderstorm development as the 500 mb temperatures are forecast to drop to around minus 8 degrees Celsius. Meanwhile, an induced surface trough will develop over the eastern Caribbean, leading to moisture pooling over the islands. As a result, there is potential for thunderstorm activity and flooding rains as a wetter and unstable pattern evolves through at least late Wednesday night. According to model guidance, there will be a quick drying trend from Thursday onwards as an upper-level ridge builds from the western Caribbean, promoting drier air intrusion and warming of the 500 mb temperatures.



AVIATION

(06Z TAFS) VFR conditions are likely across all terminals as trade wind and afternoon SHRA affect the area. Expect these conditions across TJSJ and USVI terminals throughout the period, after 12/16Z at TJBQ, and after 12/23Z at TJPS. Prevailing E-NE winds at 10-20 knots increasing to 15-25 knots between 12/13-23Z, accompanied by higher gusts and sea breeze variations. Higher winds and gusts are likely near SHRA.



MARINE

Fresh to locally strong east-northeasterly winds will continue through early Saturday morning. Embedded in this wind flow, the remnants of a front will bringing periods of passing showers and brief gusty winds across the local waters. A fading northerly swell and choppy wind-driven seas will continue to promote hazardous conditions to small craft. Please refer to the latest Marine Weather Message (MWWSJU) for detailed information. Seas are forecast to improve briefly late in the weekend into early next week.



BEACH FORECAST

Dangerous swimming and life-threatening rip currents will continue through at least Saturday across the east and north-facing beaches of PR and the USVI, due to rough surf conditions with breaking waves around 6 feet and higher at times. Given these conditions, a High Rip Current Risk remains in effect for the northwest to northeast beaches of the islands. Please refer to the latest Coastal Hazard Message (CFWSJU) and Surf Zone Forecast (SRFSJU) for detailed information. Beach goers should remain alert as a moderate risk of rip currents will continue on Sunday across across most east and northern beaches of the islands.
