More rapidly moving tropical cyclones commonly show elliptical or pear-shaped patterns in their isobars (Fig. 3.1). Any elongation in shape is normally oriented in the direction of the storm track (Visher 1925) with the ratio of longest to shortest diameter about 3:2.
In appearance, a tropical storm is like a huge whirlpool – a gigantic mass of revolving moist air. Tropical storms are between 482-644 kilometres wide and 6-8 kilometres high.
There is another tropical system off the coast of Africa that has the potential to become the next named storm in the Atlantic, according to the National Hurricane Center. Forecasters are giving this system a 20 percent chance of forming over the next five days.
What is the difference between a hurricane and a tropical storm?
Tropical Depression—A tropical cyclone with maximum sustained winds of 38 mph (33 knots) or less. Tropical Storm— A tropical cyclone with maximum sustained winds of 39 to 73 mph (34 to 63 knots). Hurricane—A tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.
Hurricanes form in the tropics where the air and water are warm and moist. Ocean water is heated and evaporates, which takes in energy from the ocean. The warm air rises quickly as it is heated and forms a low pressure system over a large area, creating tropical storms .
What tropical storm is brewing?
Three storms are currently brewing in the Atlantic: Hurricane Irma, which is set to batter the U. S. Virgin Islands and possibly Florida, tropical storm Jose, which is east of the Lesser Antilles, and tropical storm Katia, which is off the coast of Mexico.
What Hurricane is brewing now?
Tropical Rainstorm Ida is tracking across Atlantic Canada with areas of locally heavy rain. Localized flooding will continue. Hurricane Larry continues to gain wind intensity as it moves west across the tropical Atlantic Ocean.

Will Hurricane Larry hit US?
This storm will likely pass within a few hundred miles of Bermuda before hitting Atlantic Canada. Although Hurricane Larry is not likely to make a direct hit on the US, the impacts from this large and powerful storm system could be felt up and down the East Coast throughout next week.
