Tropics Watch: 1 Active System, All Moving Away From Puerto Rico

Published Sep 30, 2026 · 787 Daily · Original analysis

As of September 30, the National Hurricane Center lists 1 active Atlantic system. 0 of 1 are in Puerto Rico’s corridor or too close to dismiss; 1 is moving away.

The Atlantic is quiet for Puerto Rico this week. One named system is active, Tropical Storm Hanna, with 40 mph winds and a central pressure of 1,006 millibars. It sits 1,720 miles from San Juan and is drifting southeast at 5 mph, so the distance from the island is growing rather than shrinking. Nothing on the board falls inside Puerto Rico’s corridor or close enough to worry about.

The seven-day outlook shows no areas with a chance of development, so there is no new disturbance to track in the coming days. We are now past the climatological peak of the season, which falls on September 10, and activity typically tapers from here, though the season does not officially end until later in the fall. For now, this is a calm stretch, and everyday plans need no changes. Official guidance always comes from the National Hurricane Center and NWS San Juan, and those are the sources to check if the picture changes.
