Heavy Rains Could Affect Cuba in Coming Days

Rains associated with a trough, known as temporal storms, could occur in Cuba in the coming days due to the formation of an unstable weather zone in the northwestern Caribbean Sea, the Institute of Meteorology (Insmet) alerted today.

On its social media profiles, Insmet reminds that this type of situation is quite common during this time of year, so the trough would deepen over the Gulf of Mexico and the northwestern Caribbean, bringing a large amount of moisture to the region.

Some models suggest that, stemming from this instability, a weak low-pressure area could develop. However, at this time there is little support for cyclonic development to occur, so the probability remains very low, the scientific institution highlights.

In its report, Insmet notes that during the early days of June, the formation of weak cyclonic systems that can leave significant rains in Cuba is common.

A recent example was Tropical Storm Alex in 2022, which left intense rains and flooding in the western part of the country, although it organized as a storm east of Florida, it recalls.

For now, no clear cyclonic development is observed, and if it were to occur, it would be a weak system and the greatest impact would be rainfall, they emphasize.

Cuba lies within the impact zone of Atlantic and Caribbean cyclones and hurricanes, whose 2026 season officially begins on June 1.

Although it is forecast to have normal activity, Insmet predicted just a few days ago the possible arrival of some event during this period, which extends until November 30.

In 2025, the Caribbean nation was hit in late October by Hurricane Melissa, considered the most devastating in recent years, which made landfall east of Santiago de Cuba province with sustained winds of 194 kilometers per hour, at that time a Category 3 storm.
