Narrative updated. “Caribbean heat and drought warnings land as USVI's rains run half of normal”
Caribbean states are being urged to brace for recurrent heatwaves and drought conditions, a warning that lands squarely on the USVI as the territory's wet season underperforms. Reanalysis for 9 July–6 October 2026 shows rainfall about 51% below the 1991–2020 normal, with mean temperatures roughly 0.9°C above normal. With El Niño at +2.16 ONI and its peak impact window running June–October, the coming rains are expected to be delayed and weak, squeezing the wet season and pushing harvest risk into the dry season.
185.1 mm vs 375.7 mm normal
Reanalysis shows rainfall for 9 July–6 October 2026 running about 51% below the 1991–2020 normal, consistent with the article's warning of recurrent drought conditions across the Caribbean.
News source29.25°C mean vs 28.36°C normal
Mean temperatures over the same window ran about 0.9°C above normal, matching the article's projection of more frequent and intense heatwaves.
News sourceEl Niño typically makes United States Virgin Islands drier. Observed rainfall is running -51% — in line with the canonical response.
NASA POWER (MERRA-2) reanalysis, 9 Jul 2026 – 6 Oct 2026, sampled at the country centroid (18.4°, -64.9°). Normals are 1991–2020. How this is computed

Sector by sector
Delayed and reduced wet-season rains are expected to cut yields of rain-fed crops and push the harvest window toward the drier months.
Below-normal rainfall is likely to draw down reservoirs and cisterns, raising the risk of water restrictions across the islands.
Recurrent heatwaves raise heat-stress risk, and drier conditions can worsen air quality and waterborne disease risk where supplies dwindle.
Higher temperatures are likely to lift cooling demand and strain the grid, while drought can reduce water available for power generation.
Warmer coastal waters and heat stress are expected to shift fish stocks and stress nearshore habitats, complicating fishing schedules.

One of the strongest El Niño events on record coincided with severe Caribbean drought, prompting water rationing and crop losses in several islands.
unsourced background1997-98
Strong El Niño brought pronounced Caribbean drought and heat, stressing water supplies and rain-fed agriculture across the region.
