The Dominican Institute of Meteorology (Indomet) has released a detailed daily weather forecast for the Dominican Republic, outlining shifting conditions across the country through the day and night, alongside critical heat safety guidance and an update on a potential low-pressure system off the U.S. coast.
According to Indomet’s prediction, Sunday will open with generally favorable atmospheric conditions across most of the nation. Early morning hours will be marked by clear, mostly cloudless skies and steadily building warm temperatures that set the tone for the day. But the calm morning pattern is expected to shift as the afternoon progresses. A combination of a weak atmospheric trough and wind shear will trigger localized weather activity across three key regions: the southwest, the central mountainous Central Cordillera, and the southeastern portion of the country. These areas can expect sudden heavy downpours, a chance of scattered thunderstorms, and isolated bursts of strong wind gusts.
As night falls, weather conditions will diverge across the northern border and coastal provinces. Persistent rainfall is forecast to continue through the overnight hours in Valverde, Santiago Rodríguez, Dajabón, and Monte Cristi. For all other regions of the Dominican Republic, skies will return to mostly clear conditions with minimal cloud cover and no expected measurable precipitation.
Temperature-wise, the country will see sustained warm to hot conditions through the entire day. Maximum temperatures are projected to range between 31°C and 35°C across most territories, prompting Indomet to issue public heat safety recommendations. The agency advises residents and visitors to maintain consistent hydration by drinking sufficient water throughout the day, opt for lightweight, loose-fitting, light-colored garments that support heat dissipation, and avoid unprotected exposure to direct sunlight between the peak heating hours of 11 a.m. and 4 p.m. It also reminds the public to stay in cool, well-ventilated spaces during the hottest parts of the day.
Indomet specifically highlighted that children, older adults, and pregnant people face higher vulnerability to heat-related illness, urging communities and caregivers to monitor these groups closely for any signs of heat stress.
Beyond the daily forecast, Indomet also shared an update on a potential tropical system developing in the Atlantic. A non-tropical low-pressure system is expected to form Sunday off the U.S. East Coast, originating from a trailing cold front. The system is projected to move slowly and follow an unpredictable path over the coming week, and it has the potential to develop subtropical characteristics as it interacts with warmer ocean waters.
Current forecasts put the odds of cyclonic development very low: the chance of formation within the next 48 hours is near 0%, rising to just 30% over the full seven-day window. Crucially, Indomet confirmed that the system poses no immediate threat to the Dominican Republic at this time.
To ensure the public has access to the latest updates, Indomet is encouraging all residents to monitor changing weather conditions via its official website, indomet.gob.do, and its verified social media channels for real-time alerts and forecast adjustments.
