25th Night...11 pm






Many international agencies classify and track “Tropical Cyclone 04B” using 1‑minute average sustained winds, while IMD uses 3‑minute averages and its own classification/tracking conventions, so numbers and even timings can look different but refer to the same system.

Both methods are valid; they just follow different World Meteorological Organization–accepted practices.

Wind averaging differencesIMD defines maximum sustained wind as the highest 3‑minute mean wind at 10 m height within the cIyclone circulation.

Agencies like the U.S. National Hurricane Center and Joint Typhoon Warning Center use a 1‑minute mean wind at 10 m.Because a 1‑minute average captures shorter gusts, 1‑minute “sustained wind” values .

Tracking differencesAgencies use slightly different analysis techniques (satellite methods, model blends, weighting of observations), which can give small differences in estimated position, track, and intensity at a given time.
