SYNOPSIS

Suspended Saharan dust will be present early this week, promoting hazy skies. However, this will be short-lived as a moist and unsettled weather pattern will prevail throughout the week.

SHORT TERM
Today through Tuesday...

Persistent shower activity has been observed across Saint Croix and the northern coast of Puerto Rico all night long. However, rainfall rates were not that strong, and accumulations generally remained at around 1.5 inches for Vega Baja and below one inch elsewhere. The most recent satellite-derived precipitable water imagery show plenty of moisture in the vicinity of Saint Croix, but drier air to the northwest of Puerto Rico. This moisture field is associated with a surface trough that will gradually move over the region, once again increasing the frequency of showers. The activity should increase in the afternoon or evening hours, first spreading into St. Thomas and St. John, then Vieques, Culebra and eastern Puerto Rico. Also, showers are expected to develop due to local effects over the eastern interior and another cluster in the southwest.

The unsettled weather pattern persists on Monday as the moisture field advances into the region. At the same time, a surface high pressure migrating toward the northeast just north of the region will make the winds shift from the southeast at the surface, and from the south from 900 to 600 mb. With all that moisture and under a southern wind flow, heat indices will increase in areas that are not under the cloud shield of the trough (likely coastal areas of Puerto Rico and Saint Croix). Aside from the heat, the main focus will be the rain again, since additional showers and thunderstorms are anticipated. The light wind flow will make the activity to develop along the Cordillera Central, then spreading mostly toward the north, and possibly moving into the San Juan metro area. Soils in the interior municipalities are saturated and rivers are running high , so another round of at least urban flooding is likely.

Saharan dust will follow this rain event on Tuesday. So far, the aerosol models show that the denser cloud of dust will remain over the Caribbean waters, and reaching St. Croix, where hazy skies and periods of reduced visibilities are possible. Elsewhere, grayish skies will be possible at times, but with less concentration of dust in general.

LONG TERM
Wednesday through Sunday...

Traces of suspended Saharan dust particulates will still be present on Wednesday, leading to some hazy skies, especially during the morning hours. For the rest of the week, a wet and unstable weather pattern will persist. A series of short-wave troughs will move over the local islands throughout the week, creating favorable dynamical conditions aloft for shower and deep convective development. This will maintain 500 mb temperatures between -6 and -7 degrees Celsius and steep lapse rates for most of the long-term forecast. Meanwhile, elevated moisture levels will be present at all levels, with columnar moisture well above normal for this time of year.

Most indicators, including precipitable water and the GDI (Galvez- Davidson Index), suggest that Friday will have the highest chance of thunderstorms and heavier showers. This is when low-level moisture convergence and steep lapse rates will be at their maximum. Friday also poses the greatest potential for widespread urban and small stream flooding, as well as localized flash flooding, although similar risks will also exist on previous days with less areal coverage. As mentioned earlier, river streamflows will remain elevated, especially those across interior Puerto Rico. Therefore, any additional rainfall could lead to quick river rises in these areas. Additionally, saturated soils will enhance runoff, increasing the risk of landslides in steep terrain.

Weather conditions will gradually improve by the weekend. However, lingering moisture, coupled with diurnal heating and local effects, will continue to foster afternoon convection across interior portions of Puerto Rico and downwind of the smaller islands.



AVIATION
(06z) TAFS

SHRA will continue in the vicinity of TISX, with period of reduced VIS and low ceilings. Additional SHRA will develop after 17Z for the Cordillera Central, resulting in mountain obscuration. After 21Z, the frequency of SHRA will also increase around TJSJ and TIST. Winds will be from the ENE at 9-14 kts.



MARINE

Gentle to moderate northeasterly wind flow will continue to prevail across the local waters through at least early this week, becoming light to gentle from the east southeast on Tuesday. A small northeasterly swell will move across the Atlantic waters through the weekend. However, seas will remain less than 5 feet for the most part.

BEACH FORECAST

Moderate rip current risk will persist today, indicating the possibility of life-threatening rip currents in the surf zone, especially along north-facing beaches of the local islands. Please remember to heed the advice of the local beach patrol and flag warning systems.
