What's happening now
Hanna was a tropical storm over open water at 33.4°N, 43.8°W, moving southeast at 8 km/h in its final reading on September 30, 2026. The final reading recorded maximum sustained winds of 65 km/h, gusts of 75 km/h, and central pressure of 1,007 mb. Hanna had weakened from its peak recorded wind of 74 km/h on September 28, when pressure was 1,006 mb. Pressure rose to 1,007 mb by the final reading, while wind speed stayed at 65 km/h across the last four readings. Hanna first appeared as a tropical depression with 37 km/h winds on September 26. Hanna became a tropical storm on September 28 at 36.7°N, 51.3°W, with 74 km/h winds. RainViewer's record ends with this reading, so no later position or classification is known.

How Hanna developed
September 26 — Forms as a tropical depression
Hanna's first reading at 18:00 UTC classified the system as a tropical depression, with 37 km/h winds, 43 km/h gusts and 1,016 mb pressure. The centre was at 27.5, -58.3, in the Sargasso Sea, and the system was stationary at that time.
September 27 — Depression strengthens and begins moving
During September 27, Hanna's winds rose from 37 km/h to 56 km/h while pressure fell from 1,016 mb to 1,013 mb. Movement increased from 30 km/h to 33 km/h, and direction shifted from 3° to 33°. Readings continued to place Hanna in the Sargasso Sea.
September 28 — Pressure falls to 1,006 mb
At 06:00 UTC, Hanna remained a tropical depression with 56 km/h winds and 1,013 mb pressure. By 12:00 UTC, pressure had fallen to 1,006 mb and wind had risen to 74 km/h, a marked change in the recorded structure of the system.
September 28 — Reaches tropical-storm strength
Hanna became a tropical storm at 12:00 UTC, with 74 km/h sustained winds and 85 km/h gusts. The centre was at 36.7, -51.3 over open water, moving toward 74° at 28 km/h. This is the strongest reading on file.
How Hanna is behaving
Hanna's readings show a clear strengthening sequence. Sustained wind increased from 37 km/h to 74 km/h, while central pressure fell from 1,016 mb to 1,006 mb. Central pressure is the pressure measured near the storm's centre; a falling value accompanied by rising wind is consistent with a tightening tropical system in these observations. Gusts increased from 43 km/h to 85 km/h. The system remained a tropical depression through 06:00 UTC on September 28 before reaching tropical-storm strength six hours later.
Hanna's motion was not steady in direction. The first reading showed 0° at 0 km/h, followed by speeds from 29 km/h to 39 km/h as direction shifted from 3° through 34°. The final two readings turned from 68° to 74°, while speed changed from 31 km/h to 28 km/h. The readings establish strengthening and changing motion, but they do not identify the environmental causes.
How to track Hanna
Turn on the tropical storm tracks layer in RainViewer to follow Hanna's recorded centre positions. Each point is coloured by Hanna's classification at that moment: cyan marks a tropical depression and blue marks a tropical storm. The later hurricane categories use yellow for category 1, amber for category 2, orange for category 3, red for category 4 and dark red for category 5. Hanna's points on file are cyan through the depression stage and blue at the latest reading.
Compare the latest point with earlier points to see Hanna's movement from the Sargasso Sea readings toward the latest position over unnamed open water. The point details provide the time, position, wind, pressure and movement recorded then. RainViewer updates radar every 5 minutes, while the storm track itself reflects the available observation times. Set an alert for your area in the RainViewer app on Google Play or the App Store.
What is known about Hanna's formation in the North Atlantic
Hanna developed during the 2026 North Atlantic hurricane season, when tropical cyclones commonly form between June and November. The readings place its early centre in the Sargasso Sea and show a system that strengthened over two days. The observations do not include sea-surface temperature, moisture, wind shear or the disturbance that preceded Hanna, so the exact reason Hanna formed where and when it did is not known here.
The available record does not provide verified historical comparisons with earlier North Atlantic storms. This page therefore does not assign Hanna a historical rank or compare it with named storms from other years. The readings support a narrower conclusion: Hanna began as a tropical depression, strengthened to tropical-storm status on September 28, and reached 74 km/h in the observations supplied.
Storm FAQ
What does Hanna's 1,006 mb pressure mean?
A millibar measures atmospheric pressure. Hanna's 1,006 mb reading is the lowest central pressure in the supplied record, down from 1,016 mb at the first reading.
What is the difference between sustained wind and a gust?
Sustained wind is the storm's recorded ongoing wind speed, while a gust is a brief higher-speed burst. Hanna's latest reading lists 74 km/h sustained wind and gusts of 85 km/h.
Why are tropical storms given names?
Names make it easier to identify one tropical cyclone when several systems are being monitored in the same basin or season. Hanna is the name assigned to this North Atlantic system.
