An organized system of strong thunderstorms with stronger circulation; highest wind speed 39-73 mph. These storms can quickly accelerate when they reach tropical storm strength and become hurricanes. Storms are named when they reach tropical storm strength.
A storm of tropical origin with maximum sustained winds in the range of 34-63 knots.
a basically a hurricane, with less powerful winds
a lesser form of a hurricane
an intense thunderstorm, categorized by extremely low pressure and cyclonic wind rotation, which usually develops in the tropics
a strong tropical cyclone with less than hurricane strength
a weather system one step below a hurricane; winds from 62 to 117 km-h.
A circular low pressure system of tropical origin, with winds of 40 mph to 74 mph.
Generic term for a non-frontal synoptic scale cyclone originating over tropical or sub-tropical waters with organised convection and definite cyclonic surface wind circulation (in EM-DAT, « tropical storm » is a disaster subset of the disaster type « wind storm »).
A tropical cyclone with winds ranging from 37 to 74 miles per hour(61 to 199 KPH).
An intense area of low pressure which forms in the tropics and has sustained winds of at 39 to 73 miles per hour (34 to 63 knots). Once a tropical storm forms, it is given a name.
low pressure system forming in tropical latitudes with sustained surface wind speeds between 61 km/hr and 118 km/hr (38 and 73 mph).
A tropical depression becomes a tropical storm when its maximum sustained winds hit 39-73 miles per hour.
A tropical cyclone in which the 1-minute sustained surface wind ranges 39-73 mph. Tropical storms pose a threat to life and/or property in coastal areas.
A storm characterized by counterclockwise circulation of clouds and winds 39-73 is brewing.
A cyclonic storm having surface winds ranging from approximately 48 to 121 kilometers per hour (30 to 75 miles per hour).
Tropical cyclone with wind speeds between 35 and 64 knots.
A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 34 knot (63 km/h or 39 mph) to 63 knot (118 km/h or 73 mph).
Tropical cyclone that has maximum sustained winds from 34 to 63 knots (39 to 73 mph) inclusive.
A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 34 knots (39 mph or 63 kph) to 63 knots (73 mph or 118 kph).
Tropical cyclone with 39 to 73 mph sustained winds; it's just one step below hurricane status.
tropical cyclone with winds stronger than 27 knots but less than 66 knots
A tropical cyclone with winds of 39-73 miles per hour.
A storm with tropical characteristics that has not reached hurricane strength with winds between 39 and 73 mph.
An organized cyclone in the tropics with wind speed between 35 and 64 knots.
Tropical cyclone with winds of 39 to 74 mph. In most of the world, a storm is given a name when it reaches tropical storm intensity.
A tropical cyclone with maximum sustained surface winds 63 kilometres per hour to 117 kilometres per hour.
Maximum wind speed of 34 to 47 knots (39 to 73 mph)
A tropical cyclone in which the maximum sustained surface wind speed (using the U.S. 1-minute average) ranges from 34 kt (39 mph or 63 km/hr) to 63 kt (73 mph or 118 km/hr).
an ocean storm that forms in the tropics
A tropical cyclone with maximum sustained winds greater than 39 mph and less than 74 mph.
A cyclone with maximum sustained surface winds 39 mph to 73 mph.
tropical cyclone in which the maximum sustained surface winds are from 39 miles per hour (34 knots) to 73 miles per hour (63 knots). At this point, the system is given a name to identify and track it.
Organized thunderstorms with a cyclonic wind circulation between 35 and 64 knots.
An organized group of thunderstorms often found over a tropical ocean that generates a cyclonic flow of between 64 and 118 kilometers per hour. Often develops into a hurricane.
A hurricane goes through many stages as it develops. When the cyclonic winds have sustained speeds from 39 to 73 miles per hour, it is called a tropical storm.
A tropical cyclone in which the maximum sustained surface wind speed (1 minute average) is within the range of 39 to 73 mph (34 to 63 knots). At this point, the system is given a name to identify and track it. In the Atlantic/Caribbean/Gulf of Mexico basin, the names start with "A" each season.
