On Sunday, the Dominican Institute of Meteorology (Indomet) issued an official update warning that a low-pressure trough will shape nationwide weather conditions, bringing a period of widespread rain that will ramp up through the day and stick around for the coming days.
The wet weather is set to kick off in the early pre-dawn hours, with gradual building cloud cover and scattered light to moderate showers moving across the northwestern portion of the country by morning. Meteorologists specifically flagged Santiago Rodríguez, Montecristi, and Puerto Plata as the first provinces to see measurable rainfall as the system moves into the country.
By mid-afternoon, conditions will worsen thanks to a combination of the existing trough and daytime atmospheric warming, which will supercharge cloud development and precipitation. Forecast models call for widespread thick cloud cover, followed by moderate to heavy downpours, rolling thunderstorms, and sudden gusty winds that will last into the early evening. A long list of provinces across the north and border regions are in the highest-risk zone, including Hato Mayor, Monte Plata, Sánchez Ramírez, Duarte, Hermanas Mirabal, María Trinidad Sánchez, and Espaillat.
In response to the projected severe weather, Indomet’s National Forecast Center has issued formal weather advisories and alerts across multiple at-risk provinces. The main hazards highlighted are urban flooding, rapid rises in river and stream water levels, and an elevated risk of landslides in vulnerable terrain.
For the Greater Santo Domingo area, forecasters predict mostly scattered cloud cover through most of the day, though they note that occasional thicker cloud formation and unexpected passing showers can not be completely ruled out. Across the entire country, temperatures will remain unseasonably hot despite the cloud cover and rain, with overnight lows ranging from 22°C to 23°C and daytime highs reaching between 29°C and 31°C.
Indomet stressed that the weather pattern driven by the trough will not move on after Sunday, and that similar conditions – most notably afternoon rain and thunderstorms – will persist over the coming days. The agency has urged the general public to remain vigilant, keep updated with the latest official weather bulletins, and follow any safety guidance issued by local emergency management authorities.
