Overview of Dorian (2019)
Dorian was a tropical cyclone in the North Atlantic basin during the 2019 Atlantic hurricane season. According to official historical records archived in NOAA's International Best Track Archive for Climate Stewardship (IBTrACS v04r01), Dorian was tracked across 133 recorded observation points between August 24, 2019, and September 9, 2019.
Peak Intensity and Meteorological Measurements
In the official archive, Dorian's intensity metrics are provided by the designated World Meteorological Organization (WMO) agency for the Atlantic basin (hurdat_atl):
- Maximum sustained wind: 160.0 knots (296.3 km/h)
- Minimum central pressure: 910.0 mb
- Wind and pressure basis: WMO responsible agency (hurdat_atl)
Atmospheric pressure is measured in millibars (mb), where lower values at the center of a cyclone correspond to greater storm intensity. Dorian reached a minimum central pressure of 910.0 mb alongside its peak sustained winds of 160.0 knots.
