Question

What part of the world do hurricanes most often originate and what do they start as?

Answer 1

Off the coast of Africa is the most widely known place for development but they can occur most anywhere in the tropics.    Areas like the Yucatan Peninsula or even in the Gulf of Mexico.   Most storms moving from Africa will eventually turn NW and Northward at some point.

They usually start out as an area of distrubed weather or a tropical wave,  from there a tropical depression,  tropical storm and then Hurricane.

Answer 2

Most of the the hurricanes on the east coast develop off the coast of Africa as a tropical wave. They then go from that to a tropical depression. A tropical depression has the max wind speed of 35 mph. Once the win speeds get higher than 35 mph. it is classified as a tproical storm. The max wind speed for a tropical storm is 74 mph. A hurricane is the next class higher. 75 mph.

Here are the classes of hurricanes

CAT Winds & Effects

Surge

1 74-95 mph

(64-82 kt) 4-5 ft

  No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Also, some coastal flooding and minor pier damage.  

2 96-110 mph

(83-95 kt) 6-8 ft

  Some roofing material, door, and window damage. Considerable damage to vegetation, mobile homes, etc. Flooding damages piers and small craft in unprotected moorings may break their moorings.  

3 111-130 mph

(96-113 kt) 9-12 ft

  Some structural damage to small residences and utility buildings, with a minor amount of curtainwall failures. Mobile homes are destroyed. Flooding near the coast destroys smaller structures with larger structures damaged by floating debris. Terrain may be flooded well inland.  

4 131-155 mph

(114-135 kt) 13-18 ft

  More extensive curtainwall failures with some complete roof structure failure on small residences. Major erosion of beach areas. Terrain may be flooded well inland.  

5 155 mph+

(135+ kt) 18 ft +

  Complete roof failure on many residences and industrial buildings. Some complete building failures with small utility buildings blown over or away. Flooding causes major damage to lower floors of all structures near the shoreline. Massive evacuation of residential areas may be required.  

Most of all hurricanes can start where ever the water temp and air temp is favorable, mostly from the coast of africa, but the can start in the gulf of mexico, off the coast of the US near the Antillies or Lesser Antillies.
