Saffir simpson wind scale

The Saffir—Simpson hurricane wind scale SSHWS classifies hurricanes —which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms —into five categories distinguished by the intensities of their sustained winds. The classifications can provide some indication of the potential damage and flooding a hurricane will cause upon landfall, saffir simpson wind scale.

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based on a hurricane's sustained wind speed. This scale estimates potential property damage. Hurricanes reaching Category 3 and higher are considered major hurricanes because of their potential for significant loss of life and damage. Category 1 and 2 storms are still dangerous, however, and require preventative measures. In the western North Pacific, the term "super typhoon" is used for tropical cyclones with sustained winds exceeding mph.

Saffir simpson wind scale

The Saffir-Simpson Hurricane Wind Scale is a 1 to 5 rating based only on a hurricane's maximum sustained wind speed. This scale does not take into account other potentially deadly hazards such as storm surge, rainfall flooding, and tornadoes. Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds. Hurricanes of all categories can produce deadly storm surge, rain-induced floods, and tornadoes. These hazards require people to take protective action, including evacuating from areas vulnerable to storm surge. Disclaimer Information Quality Help Glossary. National Oceanic and Atmospheric Administration. Be Prepared! Pacific Current Season Summary C. Your browser does not support the video tag. Quick Links and Additional Resources. Very dangerous winds will produce some damage: Well-constructed frame homes could have damage to roof, shingles, vinyl siding and gutters.

USA Today.

All hurricanes are dangerous, but some are more so than others. The combination of storm surge, wind, and other factors determine the hurricane's total destructive power. The Saffir-Simpson Hurricane Wind Scale is designed to help determine wind hazards of an approaching hurricane easier for emergency officials. The scale is assigned five categories with Category 1 assigned to a minimal hurricane and Category 5 to a worst case scenario. Categories 3 to 5 are defined as major hurricanes. The criteria for each category are shown below.

The Saffir-Simpson Hurricane Wind Scale is a rating system that classifies hurricanes based on their sustained wind speed. Earth Science, Climatology, Meteorology. A home in Fort Lauderdale experiences strong winds and flooding from Hurricane Irma. South Florida felt some of the force from Hurricane Irma but it was not devastated in the same way as the Caribbean Islands. A hurricane is a tropical cyclone. Tropical cyclones are strong, rotating storms that begin over tropical oceans and bring strong winds and heavy rain. Tropical cyclones in the northwest Pacific Ocean are called typhoons.

The scale is roughly logarithmic, like the Richter Scale for earthquakes. Major hurricanes can cause devastating to catastrophic wind damage and significant loss of life simply due to the strength of their winds. Category three, four, and five hurricanes are major hurricanes and cause the most damage in the U. Customize Your Weather. The storm's flooding causes major damage to the lower floors of all structures near the shoreline, and many coastal structures can be completely flattened or washed away by the storm surge. All hurricanes are dangerous, but some are more so than others. Weather , Weather Risk Management. The scale separates hurricanes into five different categories based on wind. Tampa Bay Times. Category Five: Wind speeds greater than or equal to kilometers per hour mph Winds at this speed will cause catastrophic damage. The scale was developed in by civil engineer Herbert Saffir and meteorologist Robert Simpson , who at the time was director of the U. Homes may lose most of their roofs and some exterior walls, and most trees will be uprooted or snapped. Other areas call their tropical storms by other names, and use their own classification scales.

The Saffir—Simpson hurricane wind scale SSHWS classifies hurricanes —which in the Western Hemisphere are tropical cyclones that exceed the intensities of tropical depressions and tropical storms —into five categories distinguished by the intensities of their sustained winds.

Virtually all trees are uprooted or snapped and some may be debarked, isolating most affected communities. The U. Well-built homes could have major roof damage and many shallowly rooted trees will be uprooted and block roads. Fallen trees and power poles will isolate residential areas. Total and extremely long-lived power outages and water losses are to be expected, possibly for up to several months. The Galveston hurricane, the deadliest natural disaster at the time to hit the United States, peaked at an intensity that corresponds to a modern-day Category 4 storm. Winds at this speed will cause catastrophic damage. Additionally, terrain may be flooded well inland. Please try another search.
