Synopsis for puerto rico and the uS. Virgin islands waters - . A strong surface ridge over the north-central atlantic and weakening surface trough will continue to generate moderate to fresh east- northeasterly winds. A fading northerly swell and choppy wind-driven seas will continue to promote confused seas. An upper-level trough and induced surface trough will promote inclement weather across the local waters by early next week.

Area Forecast Discussion...DELAYED National Weather Service San Juan PR 524 PM AST Sat Apr 13 2024

SYNOPSIS

Fair weather conditions will persist through early tomorrow before a wet weather pattern returns by Sunday afternoon. An upper-level trough will increase the potential of thunderstorm activity, leading to heavy rainfall by early next week. This will heighten the risk of flooding and landslides across the area.

SHORT TERM
Tonight through Monday...

Satellite and radar data detected large cloud coverage and rain showers, mostly in the Caribbean waters and southern sections of Puerto Rico, moving westward by early morning. As drier air started to filter in, shower activity gradually diminished. However, a streamer developed very early in the morning from St. Thomas to northeastern Puerto Rico, including the northern tip of San Juan.
Moderate to heavy rain affected a very small portion of the area, while the rest experienced mostly fair weather conditions. Up to two- tenths of an inch fell with this activity.

After this morning's activity, satellite data indicated precipitable water of 1.14 inches over the local area from a drier slot moving in. Therefore, mostly fair weather conditions prevailed in the afternoon hours, with a few showers noted across southwestern Puerto Rico. Breezy wind conditions were also present. We can expect fair weather conditions to persist through at least tomorrow with a few isolated showers over windward coastal areas.

On Sunday, a transition to a wet weather pattern is expected.
Ridging aloft will persist, maintaining dry and stable conditions at upper levels, which will inhibit deep convective activity for the most part. However, at low levels, moisture will increase drastically. A broad area with high precipitable water detected by GOES-16 satellite imagery is currently just east of the Leeward Islands. The CIRA Layered Precipitable Water product indicates that high moisture content is present, at least up to 500 mb within this area. The easterly trades will advect this moister airmass over the region by late Sunday morning and persist through the short-term forecast. This will cause an increase in cloudiness and areal coverage of shower activity, particularly after 15z. Hi-res models indicate that most activity will cluster across eastern, interior, and western/southwestern portions of Puerto Rico. At most, ponding of water in roads and poorly drained areas can be expected.

By Monday, an upper-level trough and an induced surface trough will combine with this moister airmass, increasing unstable weather conditions across the CWA The GFS Galvez-Davison Index indicates the potential for isolated to scattered thunderstorms over the northeastern Caribbean, particularly by late Monday. Therefore, expect an increased potential of urban and small stream flooding, with possible isolated flash flooding events. Landslides and rockfalls from this activity are also possible, particularly in areas with steep terrain.




LONG TERM
Tuesday through Saturday...

PREV DISCUSSION
/issued 458 AM AST Sat Apr 13 2024/

Tuesday through at least Wednesday a very moist and unstable environment will persist due to the presence of the mid to upper trough crossing into the northeastern Caribbean then lingering over the area through midweek. This will provide good ventilation and divergence aloft along with strong dynamics for thunderstorm development, as the 500 mb advective temperatures are forecast to range between minus 7 to minus 9 degrees Celsius. Meanwhile, increasing moisture convergence and pooling is forecast due to an induced surface trough and the dominant east southeast winds. As a result, the potential for thunderstorm development and flooding rains will be high as this wetter and unstable pattern will evolve and continue through at least Wednesday. Based on most recent GFS model guidance which has been initializing fairly well, there will be a gradual drying trend from Thursday onwards as a mid to upper- level ridge builds from the western Caribbean, and a surface high pressure ridge builds across the west Atlantic. This will promote east to northeast winds once again, with winds becoming more easterly by the following weekend.
This expected pattern will also lead to an overall drier airmass across the region at least Thursday through Friday, followed by the return of occasional passing trade wind showers and more isolated to scatters afternoon showers in and around the islands over the weekend.

AVIATION
(18z)

Mainly VFR conditions expected to continue. SHRA are expected to increase after 22Z around the USVI, approaching eastern PR around 10Z. Brief periods of reduced VIS and low ceilings are possible.
Winds will be from the ENE at 15-18kts, slowing down after 22z, below 13 kts. Winds will pick up again after 14/13-14Z.

MARINE

A strong surface ridge over the north-central Atlantic and weakening surface trough will continue to generate moderate to fresh east- northeasterly winds. A fading northerly swell and choppy wind- driven seas will continue to promote confused seas. An upper-level trough and induced surface trough will promote shower and thunderstorm activity across the local waters by early next week.

BEACH FORECAST

Pulses of a weak north-northeasterly swell will continue to invade the northern regional waters through the weekend. Additionally wind-driven seas and rough surf conditions will contribute to hazardous breaking waves of 6 feet. As a result, the Rip Current Statement was extended through late Sunday night for all beaches across the northern coastline of Puerto Rico and Culebra. For more information and details please refer to the latest Surf Zone Forecast (SRFSJU), and the Coastal Hazard Message product (CFWSJU).
