Beginning the 2010 hurricane season, which runs from June 1 – November 30 for the Atlantic Basin (i.e. Atlantic Ocean, Caribbean Sea, Gulf of Mexico), the National Hurricane Center will be categorizing storms using a new version of the Saffir-Simpson scale.
The new Saffir-Simpson Hurricane Wind Scale will keep the same wind speed ranges as the original Saffir-Simpson Scale for each of the five hurricane categories, but no longer ties specific storm surge and flooding effects to each category.
The modification to the previous scale comes as realizations were made that storm surge values and associated flooding are dependent on a combination of the storm’s intensity, size, motion and barometric pressure, as well as the depth of the near-shore waters and local topographical features. The National Hurricane Center says storm surge forecasts will continue to be included in hurricane advisories.
If you live in a hurricane prone area, below are the categories you should become familiar with:
Category One (Sustained winds 74-95 mph) – Severe winds will produce some damage and minor flooding is possible. Example: Humberto, 2007
Category Two (Sustained winds 96-110 mph) – Dangerous winds and moderate flooding will cause extensive damage. Example: Dolly, 2008
Category Three (Sustained winds 111-130 mph) – Extremely dangerous winds and significant flooding will cause devastating damage to occur. Example: Fran, 1996
Category Four (Sustained winds 131-155 mph) – As a result of destructive winds and flooding catastrophic damage will occur with very few structures remaining. Example: Charley, 2004
Category Five (Sustained winds greater than 155 mph) – Unfathomable winds speeds and flooding will cause mass catastrophic damage to occur and structures will be left in ruins. Example: Katrina, 2005
Stay tuned! In early April the official 2010 Atlantic Hurricane Season forecast will be released. You can bet The Northeast Quadrant will be on top of it!
