The Miami, Florida-based National Hurricane Center (NHC), is monitoring two areas for potential tropical development within the Atlantic Hurricane Basin. One is off the South Carolina/Georgia coast while the other is just north of the coast of South America. Fortunately, the NHC doesn’t expect much in the way of tropical cyclone formation from either of these systems. However, they can still be problematic.
The closest system to the United States is a non-tropical low pressure area located about 150 miles south-southeast of the North Carolina/South Carolina border. It continues to produce disorganized showers and thunderstorms over portions of southeastern and eastern North Carolina, including the Outer Banks, and adjacent Atlantic waters. According to the NHC, a northward motion is forecast to begin by this evening. However, the NHC says that environmental conditions are expected to remain unfavorable for significant development through tonight when the low will move inland over eastern North Carolina. While the NHC says there’s only a 10% chance of tropical cyclone formation here, there is a high chance that very heavy rain will persist over nearby areas of the Mid Atlantic.
The second system being monitored is located a few hundred miles east of Trinidad and Tobago. Showers and thunderstorms there are associated with a westward-moving tropical wave. According to the NHC, some slow development of this system is possible over the next couple of days before upper level winds become less conducive and the system begins to interact with the landmass of South America. Like the system close to the U.S. east coast, the NHC says there’s only a 10% chance that a tropical cyclone will form here. However, regardless of development, this system could produce gusty winds and heavy rainfall over Trinidad and Tobago and the northeastern coastal sections of Venezuela through the next several days.
Elsewhere, the tropics are quiet in the Atlantic basin; the NHC expects no other systems to develop over the next 5 days here.
The 2020 Atlantic hurricane season runs through to the end of November.
