Synopsis for puerto rico and the uS. Virgin islands waters - . A surface ridge over the north-central atlantic and broad surface trough across the eastern caribbean will generate moderate to locally fresh east-northeasterly winds. A fading northerly swell and the choppy wind driven seas will continue to promote confused seas tonight and tomorrow. An approaching upper level trough and induced surface trough will continue to promote inclement weather across the local waters tonight and into midweek of this week.

SYNOPSIS

An unstable and wet pattern will lead to limited to moderate excessive rainfall hazard levels or flooding impacts in the coming days. Additionally, hazardous marine and life-threatening surf zone conditions will persist.

SHORT TERM
Tonight through Tuesday...

Showers affected windward coastal areas during the early morning hours before dissipating for the remainder of the morning. These showers left less than a tenth of an inch across northeastern portions of Puerto Rico, Culebra, and the northern USVI.

By noon, the leading edge of a surface-induced perturbation was approaching the CWA from the east. By early afternoon, gradually increasing cloud coverage and shower activity began to affect the USVI, northeastern, interior, and western/southwestern Puerto Rico.
The latest imagery from the Polar Blended-Percent of Normal Total Precipitable Water (TPW) indicates between 150%-165% above normal TPW spread between PR and the northeastern Leeward Islands.
Therefore, higher moisture will continue to stream across the area this evening and tomorrow. Despite the higher moisture content and low-level instability brought by the surface perturbation, convective activity has remained shallow for the most part. The Doppler radar estimated up to 0.50 inches of rain across northern and northeastern Puerto Rico, mostly over the Luquillo mountain range, and up to 1.5 inches of rain between Yauco and Maricao.
Expect this activity to continue this evening and late tonight.

For Monday and Tuesday, weather conditions will become even more unstable as an upper-level trough approaches from the northwest,combining with high low-level moisture, causing the mid-level ridge to erode and promoting cold air advection over the local islands. The 500 mb temperatures will drop to -9.0 degrees Celsius by midweek, promoting steep temperature lapse rates across the region. The GFS Galvez-Davison Index suggests the potential for isolated to scattered thunderstorms with the possibility of heavy rainfall. The ECMWF Precipitation Extreme Forecast Index (EFI) suggests high confidence among its ensemble members in predicting above-normal precipitation for this time of year through midweek.

Despite the area with higher moisture convergence being expected north of Puerto Rico, wet and unstable weather conditions will combine with diurnal heating and local effects, further increasing the potential for downpours throughout the remainder of the short- term forecast. Very localized convergence zones capable of producing prolonged heavy showers cannot be ruled out, posing particular risks for urban and flood-prone areas. Quick river rises, flash flooding, and landslides are likely in the coming days.

LONG TERM
Wednesday through Sunday...

PREV DISCUSSION
/issued 505 AM AST Sun Apr 14 2024/

Wednesday through at least early Thursday morning, inclement weather and a moist and unstable environment will persist due to the lingering mid to upper trough crossing into the northeastern Caribbean. This will provide good ventilation aloft along with the advective low level moisture pooling for a continued showery pattern and isolated thunderstorm development. The low level moisture convergence caused by the east southeast winds and local and diurnal effects will favor good potential for thunderstorm development and flooding rains at least until late Wednesday or early Thursday. Thereafter, recent model guidance continued to initialize well and still suggest moisture erosion with increasing stable conditions aloft by Thursday afternoon.
A gradual drying trend is expected from then onwards, as a mid to upper- level ridge will build northwards from the western Caribbean, and a surface high pressure ridge builds across the west Atlantic. This in will bring a return of east-northeast winds once again through Friday, followed by winds becoming more easterly and increasing over the following weekend. This expected pattern will also lead to an overall drier airmass at least Thursday through Friday, followed by the return of occasional passing trade wind showers and more typical isolated to scattered afternoon showers in and around the islands over the weekend.

AVIATION
(18z)

SHRA are expected to increase through the forecast period. Periods of reduced VIS and low ceilings are possible with the activity, especially for USVI terminals and TJSJ. After 22z, TSRA expected to develop in the local waters, mostly around the USVI. Mountain obscuration expected after 13-14Z for the Cordillera Central. VCTS also expected after 15/17Z for TJBQ. Winds will be from the ESE at 14-19 kts, with stronger gusts.



MARINE

A surface ridge over the north-central Atlantic and broad surface trough across the eastern Caribbean will generate moderate to locally fresh east- northeasterly winds. A fading northerly swell and the choppy wind driven seas will continue to promote confused seas tonight and tomorrow. An approaching upper level trough and induced surface trough will continue to promote inclement weather across the local waters tonight and into midweek of this week.



BEACH FORECAST

Atlantic Nearshore buoys continue to indicate breaking waves above 6 feet. Additionally, pulses of a weak northeasterly swell will continue to affect the northern regional waters through the workweek. Consequently, the Rip Current Statement will remain in effect for all beaches along 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).



HYDROLOGY

PREV DISCUSSION
/issued 1009 AM AST Sun Apr 14 2024/

A wet pattern is expected to begin today and stretch into the middle of the week. An area of enhanced moisture (surface trough)
will combine with an upper level trough, resulting in unsettled weather conditions. The risk of urban and small stream flooding, water surges, mudslides and isolated flash flooding will increase.
The areas most affected are expected to be eastern and northern half of Puerto Rico, as well as the interior. The Virgin Islands and southern Puerto Rico will receive pulses of showers and thunderstorms as well. Conditions are expected to improve by Thursday. A Hydrologic Outlook (ESFSJU) will be issue later today.

SJU WATCHES/WARNINGS/ADVISORIES
PR...High Rip Current Risk through Monday afternoon for PRZ001-002- 005-008-012.

VI...None.
AM...Small Craft Advisory until 6 PM AST Tuesday for AMZ711.

Small Craft Advisory until 6 PM AST Monday for AMZ723.
