Santo Domingo – The Dominican Institute of Meteorology (Indomet) has announced the commencement of the frontal season in the Dominican Republic this November, which is expected to bring increased rainfall, northerly winds, and cooler temperatures, particularly after frontal systems pass. This season typically lasts until mid-April.
During this period, the country typically experiences an average of seven to eight cold fronts, although this can fluctuate based on atmospheric conditions. These cold fronts occur when a mass of colder air moves in, displacing warmer air, which leads to increased cloudiness, rainfall, and a drop in temperatures.
Regions most likely to experience rainfall from these cold fronts include the northwest, north, and northeast areas of the country, as well as the northern slopes of the Central Mountain Range. Other regions may also see some precipitation.
Cooler nights and mornings ahead
Indomet reported that temperatures are expected to gradually decrease throughout the season, particularly during the night and early morning, as well as following the passage of the cold fronts. Communities in mountainous areas, including Valle Nuevo, Constanza, Hondo Valle, Rancho Arriba, and Polo, are anticipated to experience the coldest conditions. While coastal and lowland areas may still enjoy warm afternoons, overall temperatures will remain below those typical for the hottest months.
Additionally, forecasts from the NOAA Climate Prediction Center suggest that rainfall may be above normal, especially in the northwest, north, northeast, and the northern slope of the Central Mountain Range.
Indomet also reminded the public that the onset of the frontal season does not preclude the possibility of tropical cyclones developing. The Atlantic hurricane season officially continues through November 30, and residents are urged to stay informed through official forecasts regarding potential storms and heavy rainfall that could lead to flooding.
