Classification of Hurricanes

The Saffir Simpson Scale is used to classify Hurricanes according to intensity. In this scale, hurricanes are grouped into one of five categories as shown below, with category 5 being the most destructive.


Saffir/Simpson Hurricane Scale


Central Pressure
Mean (millibars)



Surge (ft)



980  or more

74 - 95mph (119 - 151km/h)


Damage mostly to poorly constructed signs, trees, foliage, and unanchored homes, low lying coastal roads flooded, minor pier damage, etc. No real damage to other structures.
Summary: Very dangerous winds will produce some damage


965 - 979

96 - 110mph (152 - 176km/h)


Tree blown down, considerable damage to shrubbery, poorly constructed signs, mobile homes, roofing material, windows, doors and piers. NO major damage to buildings but evacuation of some coastline residences will be likely.

Summary: Extremely dangerous winds will cause extensive damage


945 - 964

111-130mph (177 - 209km/h)


Practically all poorly constructed signs destroyed, foliage torn from trees, large trees blown down, damage to roofing materials and structural damage to small buildings. Serious flooding at coast, with many smaller structures near coast destroyed. Evacuation of residences near shoreline required.
Summary: Devastating damage will occur


920 - 944

131 - 155mph (210 - 248km/h)


All signs down, shrubs and trees blown down, extensive damage to roofs, windows and doors. Major damage to lower floors of structures near shore due to flooding and battering by waves and floating debris. Major erosion of beaches, flat terrain 10 feet or less above sea level flooded inland as far as 6 miles. Massive evacuation of all residences within 500 yards of shore and of single story residences within 2 miles of shore.
Summary: Catastrophic damage will occur )


less than 920

more than 155mph (248km/h)

more than 18

Complete failure of roofs, on many residences and buildings, severe damage to windows and doors and glass structures, some complete building collapse. Low lying escape routes cut by flooding, massive evacuation of residential areas on low ground within 5-10 miles likely.
Summary: Catastrophic damage will occur

Hurricane season in the Atlantic lasts from June 1st to November 30th.
Tropical storms are given male and female names because this makes them easier to track. Before 1979 though, they only had female names.
A tropical storm becomes a hurricane when its winds reach 74 mph or higher.
Hurricanes are grouped into 5 categories according to their strength. Category 5 hurricanes are the strongest.
The “eye” is the centre of the hurricane and is the calmest part.
Slow moving hurricanes produce more rain and can cause more damage from flooding.
Putting tape on windows and glass will not stop them from breaking during a hurricane.
The word hurricane comes from the word Hurakan. Hurakan is the name of the Mayan god of wind and fire.
