Overview

• Tropical Storm Dexter is moving northeast over the open Atlantic with sustained winds of 74 km/h and gusts up to 93 km/h; it is forecast to transition into a post-tropical cyclone by August 6–7.
• Tropical Storm Henriette lies about 1,440 km southwest of Cabo San Lucas with 75 km/h winds and 95 km/h gusts; it is projected to weaken without reaching hurricane strength and dissipate by August 9.
• The National Hurricane Center and Conagua confirm neither storm poses a threat to U.S. or Mexican coastlines.
• European model ensembles indicate that upper-level wind shear over the tropical Atlantic will weaken around mid-August, creating more favorable conditions for storm development.
• Neutral ENSO conditions and Madden–Julian Oscillation patterns are supporting forecasts for above-average cyclone activity in both the Atlantic and Pacific basins.
