The National Hurricane Center (NHC) has released information regarding a low-pressure trough moving westward near the Greater Antilles, which is currently causing rainfall over Hispaniola. According to the NHC's latest bulletin, "disorganized showers and thunderstorms persist in association with a low-pressure trough extending from near Hispaniola northeastward over the southwestern Atlantic."
Despite the weather activity, the NHC has reduced the chances of this system developing into a stronger storm to 10 percent over both the next 48 hours and the upcoming week. The meteorological organization noted that "regardless of development, locally heavy rainfall is possible over the Virgin Islands, Puerto Rico, Hispaniola, the Turks and Caicos Islands, and the southeastern Bahamas through Sunday."
Potential Impact on the Caribbean
Currently, Cuba is not listed among the areas anticipated to be impacted. The NHC stated, "Any development of this system should occur slowly over the next few days as it moves west to west-northwest near the Greater Antilles, the Turks and Caicos, and the southeastern Bahamas."
A trough is defined as an elongated region of relatively low atmospheric pressure extending from a low-pressure area into areas of higher pressure. These systems are typically associated with atmospheric instability, which frequently leads to air rising, cloud formation, and often precipitation and storms.
The Role of Troughs in Weather Changes
In meteorological terms, troughs are vital indicators of areas prone to weather changes, including rain and temperature shifts. They can develop in any region, affecting both tropical climates and mid-latitude areas. It's important to note that the current hurricane season is set to conclude on November 30.
