Guide to Understanding Hurricane Intensity and Warning Criteria

Discussion started by JarydMore17 10 months ago

Who can forget the infamous Super Storm Sandy that made an almost 90 degree turn into the state of New Jersey in October 2012.

This historic and unprecendent storm left not only the public,but meterologists and forecasters across the country in awe. Weather can humble us all at times. To be quite honest, the unpredictibity and danger that can accompany a weather system is still very much a concern today. Although technology and innovation in the weather iundustry has grown tremendously, the probability for error will always exist.

That being said, The single most important thing that we can do as forecasters, is to warn the public of impending weather hazards and save as many lives as possible. Whether or not that system actually lives up to its potential is quite frankly not something we can control. 

One of the most destrructive, deadly,and costly storm that threatens the United States each year, is Tropical Cyclones. Below, we are going to disect the Saffir Simpson scale, watches and warnings, and the criteria that must be met for Hurricanes.

Hurricane / Tropical Storm Alerts (According the NWS)

    • Tropical Storm Watch: An announcement that tropical-storm conditions are possible within the specified area.
    • Hurricane Watch: An announcement that hurricane conditions are possible within the specified area.

Because outside preparedness activities become difficult once winds reach tropical storm force, watches are issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.

Action: During a watch, prepare your home and review your plan for evacuation in case a Hurricane or Tropical Storm Warning is issued. Listen closely to instructions from local officials.

    • Tropical Storm Warning: An announcement that tropical-storm conditions are expected within the specified area.
    • Hurricane Warning: An announcement that hurricane conditions are expected within the specified area.

Because outside preparedness activities become difficult once winds reach tropical storm force, warnings are issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.

Action: During a warning, complete storm preparations and immediately leave the threatened area if directed by local officials.

  • Extreme Wind Warning - Extreme sustained winds of a major hurricane (115 mph or greater), usually associated with the eyewall, are expected to begin within an hour.

    Action: Take immediate shelter in the interior portion of a well-built structure.

Additional Watches and Warnings may be issued to provide detailed information on specific threats such as floods and tornadoes. Local National Weather Service offices issue Flash Flood/Flood Watches and Warnings as well as Tornado Warnings.
