What is a Hurricane?
A severe tropical cyclone with sustained winds of 74 mph (64 knots) or greater is a Hurricane
. Major hazards include high winds, heavy rainfall, flooding, storm surge and high surf. Hurricane is the term used for systems located in the central and eastern Pacific regions. Systems of this intensity occurring in the western Pacific are called typhoons. Five categories for hurricanes
of various intensities have been established.What to do to Protect YourselfThe basic things to do:

Hurricane Watch is issued for a coastal area when there is a threat of hurricane conditions within 24-36 hours.Hurricane Warning
is issued when hurricane conditions are expected in a specified coastal area in 24 hours or less. Hurricane conditions include winds of 74 miles an hour (64 knots) and/or dangerously high tides and waves. Actions for protection of life and property should begin immediately when the warning is issued.Small craft cautionary statements.
When a tropical cyclone threatens a coastal area, small craft operators are advised to remain in port or not to venture into the open sea.Storm Warnings

The Joint Typhoon Warning Center classifies typhoons with wind speeds of 150 mph or more (the equivalent to a strong Category 4 storm) as a Super Typhoon Tropical cyclone
is the general term for all cyclone circulations that originate over tropical waters.Tropical disturbance:
Moving area of thunder storms in the tropics that maintain an identity for 24-hours or more.Tropical depression:
Rotary circulation at surface highest constant wind speed 38 miles per hour (33 knots).Tropical storm
: Distinct rotary circulation, constant wind speed ranges 39-73 miles per hour (34-63 knots).Typhoon
A typhoon is a large and powerful tropical cyclone, a low pressure area rotating counterclockwise and containing rising warm air that forms over warm water in the Western Pacific Ocean. Less powerful tropical cyclones are called Tropical Depressions and Tropical Storms.
