Tropical Storm Humberto 2025

Tropical Storm Humberto

Live tracking map, satellite images and forecasts of Tropical Storm Humberto 2025 in the central Atlantic Ocean. Current wind speed 60mph. Max 120mph.

Humberto continues to gradually gain strength over the central Atlantic. Deep convection has been increasing over the center, and the cloud pattern is more symmetric than it was earlier today (25 September). This is an indication that the wind shear around the storm is lessening. Recent microwave images indicate that an inner core appears to be forming, and an earlier ASCAT pass showed maximum winds of about 50 mph (45 knots). Based on the improving satellite presentation, the initial intensity is increased to 60 mph (50 knots). This value is also near the average of the latest satellite intensity estimates. The 34-knots wind radii have been adjusted based on the ASCAT data.

Steady to rapid strengthening is expected during the next few days as the storm moves into a more favorable environment of light winds aloft and high moisture. Given that Humberto is relatively compact and an increasingly symmetric system, these conditions should cause it to become a hurricane on Friday and a major hurricane over the weekend. Less favorable environmental conditions should cause some weakening early next week. This prediction remains in line with the latest HCCA and IVCN consensus models.

The storm has jogged a little to the north today, but the overall motion is northwestward at 5 mph (5 knots). Humberto remains embedded in weak steering currents on the south side of a narrow and weak subtropical high over the central Atlantic. This pattern should keep the storm moving slowly to the west-northwest or northwest during the next day or two. After that time, Humberto is expected to become increasingly steered by a much stronger high over the western Atlantic, which should cause the storm to accelerate. The NHC track forecast is a little slower than the previous one, trending toward the latest consensus and Google Deep Mind models. This forecast keeps Humberto over the open central and western subtropical Atlantic during the next several days.
