What winds make a tropical storm?
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).
What is hurricane strength winds?
To be classified as a hurricane, a tropical cyclone must have one-minute-average maximum sustained winds at 10 m above the surface of at least 74 mph (Category 1). The highest classification in the scale, Category 5, consists of storms with sustained winds of at least 157 mph.
How tropical storms develop?
Tropical storms usually form between 5° and 30° latitude. When the ocean surface waters reaches at least 27°C due to solar heating, the warm air above the water rises quickly, causing an area of very low pressure. As the air rises quickly more warm moist air is drawn upwards from above the ocean creating strong winds.
When did it start to become a tropical storm?
When the wind speeds reach 39 mph, the tropical depression becomes a tropical storm.
What are hurricane gusts?
Hurricane winds 110 to 130 mph gusts 140+ mph: Catastrophic damage expected to man-made and natural structures. Well constructed homes will have substantial damage to roof and walls. … Hurricane winds – 130 to 160 mph gusts 170+ mph: Devastating damage is expected.
Where are the strongest winds in a hurricane?
Strongest winds ( and hurricane-induced tornadoes) are almost always found in or near the right front (or forward) quadrant of the storm because the forward speed of the hurricane is added to the rotational wind speeds generated by the storm itself.
