What is the Difference Between a Hurricane and a Typhoon? They are called hurricanes in the Atlantic Ocean, Caribbean, Gulf of Mexico, and eastern Pacific Ocean. But once you go west across the International Dateline and into the western Pacific Ocean, they're called typhoons.
Hurricane/Typhoon Facts
When a storm is approaching, be sure to do the following:
During the storm, be sure to do the following:
After the hurricane has passed the sense of relief can be overwhelming, but additional caution is necessary to avoid dangerous situations from the storm's damage.
An organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds of 38 mph (33 knots) or less. Sustained winds are defined as one-minute average wind measured at about 33 feet (10 meters) above the surface.
An organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of 39-73 mph (34-63 knots).
An intense tropical weather system of strong thunderstorms with a well-defined surface circulation and maximum sustained winds of 74 mph (64 knots) or higher.
A dome of water pushed onshore by hurricane and tropical storm winds. Storm surges can reach 25 feet high and be 50-1,000 miles wide.
A combination of storm surge and the normal tide (i.e., a 15-foot storm surge combined with a 2-foot normal high tide over the mean sea level created a 17-foot storm tide.)
Hurricane and tropical storm conditions are expected in the specified area, usually within 24 hours.
These warnings provide detailed information about specific hurricane threats.
Hurricane/Typhoon Watch - Issued when there is a threat of hurricane conditions within 48 hours or less. Hurricane/Typhoon Warning - Issued when hurricane conditions are expected in 36 hours or less.
Indicates surface winds in excess of 58 mph (50 knots) could arrive within 96 hours.
Indicates surface winds in excess of 58 mph (50 knots) could arrive within 72 hours.
Indicates surface winds in excess of 58 mph could arrive within 48 hours.
Indicates surface winds in excess of 58 mph could arrive within 24 hours.
Indicates surface winds in excess of 58 mph could arrive within 12 hours.
Winds of 40-57 mph/35-49 knots sustained are occurring.
Winds of 58 mph/50 knots sustained and/or gusts of 69 mph/60 kts or greater are occurring. All outside activity is strictly prohibited.
Destructive winds have subsided and are no longer forecast to occur; survey and work crews are permitted to determine the extent of the damage and to establish safe zones around hazards (e.g. downed power lines, unstable structures). Non-essential personnel are asked to remain indoors.
