SYNOPSIS...

Unsettled weather conditions are expected to prevail the rest of the afternoon hours, with an elevated risk of flooding, especially across southwestern Puerto Rico with improving conditions tonight. Additional shower development should continue tomorrow.
Some improvement is anticipated for the first couple of days of the workweek, but the pattern will turn wet again around mid-week, with additional periods of showers and thunderstorms. Marine and coastal conditions are expected to deteriorate Monday onwards as a northerly swell arrives.

SHORT TERM
Tonight through Monday

Another day with cloudy skies across the forecast area. During the morning hours, isolated showers moved across northern, eastern, and central sections of Puerto Rico, as well as the U.S.
Virgin Islands. Easterly winds between 5 to 10 mph turned more from the northeast through the day under the influence of a building surface high pressure across the western Atlantic.
Daytime highs peaked mainly in the mid to upper 80s along coastal areas and 70s to lower 80s across the Cordillera Central. During the early afternoon hours, showers and thunderstorms began to develop across the southwestern quadrant of Puerto Rico, where a flood advisory was issued. At this time, the highest rainfall accumulations are around 2.00 to 4.00 inches of rain along that region based on radar estimates.

Tonight, expect variable conditions to continue with isolated to scattered showers. The associated moisture and rainfall activity will filter across the northern and eastern sectors of Puerto Rico and the surrounding waters. Precipitable water levels should remain above normal values most of the day on Sunday, resulting in additional showers and isolated thunderstorms possible. High resolution models are showing best rain chances across the northeastern and the interior of PR during the morning, then moving to the southwest by the afternoon.

Based on the latest model guidance, at the beginning of the workweek, the broad high pressure is expected to help push the moisture field southward allowing a slightly drier airmass to filter into the local islands. However, Precipitable Water models suggest that moisture levels will not drop that much and remain around seasonal levels.
That should result in at least some convection across the interior and southwestern Puerto Rico due to the prevailing northeasterly winds and local effects, but accumulations should be much less in comparison with the last couple of days.

LONG TERM
Tuesday through Saturday

PREV DISCUSSION
/issued 400 AM AST Sat Apr 27 2024/

A high pressure system at the lower levels of the atmosphere will drive the winds from the east at the surface, and from the northeast a little bit aloft. This feature will maintain the moisture trapped in the lower levels of the atmosphere. In general, Tuesday looks like the driest day of the forecast period, but moisture will still remain at seasonal levels, triggering convection in the interior and southwestern Puerto Rico.

The pattern will turn wet again for the rest of the workweek as yet another mid and upper level trough digs into the western Caribbean.
This trough will pull plenty of moisture from the Caribbean Sea into the local islands, and precipitable water values will be above normal. On Wednesday, the steering flow will be from the southeast, so local effects should trigger for the interior, north and northwest of Puerto Rico, as well as around the Virgin Islands and local waters. Then, on Thursday, as the trough further approaches, the steering winds will collapse, with very light winds anticipated.
Additionally, the mean flow will be from the southwest, so activity could switch focus for the eastern interior, the San Juan metro area, and then the Virgin Islands.

One thing that could delay the development of rain, however, is that if a thick cloud layer get established, then local effects will be milder. Also, temperatures could be below normal for a change, except for the southern coast of Puerto Rico, where values are still expected to reach the low 90s. On the other hand, if there are breaks of sunshine, then the risk for showers and thunderstorms will be elevated, likely producing urban and small stream flooding, water surges along rivers, as well as mudslides.

By Friday, the influence of the mid and upper level trough diminishes, but a surface reflection remains, maintaining enough moisture, and a light wind flow from the northeast. More moisture will also be added into the mixture from another trough approaching the eastern Caribbean from the east. Thus, another active afternoon is anticipated for the interior of Puerto Rico, with activity then spreading toward the coastal areas. Since some drier air will filter at the mid and upper levels, temperatures will warm up again to more seasonal values, reaching the mid and upper 80s, and even the low 90s.

On Saturday, the pressure gradient begins to recover as a surface high pressure exits the eastern coast of the United States. The winds will be around 10 knots, and out of the southeast. Lingering moisture around the northeastern Caribbean will maintain a showery pattern, with another active afternoon and an elevated risk for flooding and mudslides.

AVIATION...
(18z TAFs)

SHRA will end at TJPS before 28/00z, but passing SHRA are anticipated to continue across the local waters, reaching the USVI and TJSJ terminals after 06Z. Periods of reduced VIS and low ceilings are anticipated. Additional round of SHRA and VCTS is anticipated for TJPS after 28/17Z. Mountain obscuration is expected for the Cordillera Central from 14-21Z. Winds will be on the increase, out of the NE at 11-16 kts, and stronger gusts after 28/13- 14Z.

MARINE...

Showers and thunderstorms will continue to affect the local waters for the next several days as lingering moisture from a surface trough/old frontal boundary remains over the local area. Gentle to moderate northeast winds will continue tonight and Sunday morning.
Winds will increase from moderate to fresh Sunday night through at least Tuesday night under the influence of a surface high pressure moving off the eastern coast of the United States. A northerly swell is anticipated to spread across the local waters Monday deteriorating coastal and marine conditions through at least mid- week.

BEACH FORECAST...

Breaking waves around 5 feet will maintain the risk of rip currents moderate through tomorrow along the north-facing beaches of Puerto Rico and the U.S. Virgin Islands. A northerly swell will be arriving on Monday, increasing the risk for these beaches to high through at least late Wednesday.
