Storm Data is an official publication of the National Oceanic and Atmospheric Administration (NOAA NOAA
National Oceanic and Atmospheric Administration
Noun 1. NOAA - an agency in the Department of Commerce that maps the oceans and conserves their living resources; predicts changes to the earth's environment; ) which documents the occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, and/or disruption to commerce. In addition, it is a partial record of other significant meteorological me·te·or·ol·o·gy
The science that deals with the phenomena of the atmosphere, especially weather and weather conditions.
[French météorologie, from Greek events, such as record maximum or minimum temperatures or precipitation that occurs in connection with another event.
Some of the information appearing in Storm Data may have been provided by or gathered from sources outside the National Weather Service (NWS NWS National Weather Service
NWS Naval Weapons Station
NWS New World Symphony
NWS Nuclear Weapon State
NWS Not Work Safe
NWS National Watercolor Society
NWS North Warning System
NWS Nose Wheel Steering
NWS National Waste Strategy (UK) ), such as the media, law enforcement and/or other government agencies, private companies, individuals, etc. An effort is made to use the best available information, but because of time and resource constraints, information from these sources may be unverified by the NWS. Therefore, when using information from Storm Data, customers should be cautious as the NWS does not guarantee the accuracy or validity of the information. Further, when it is apparent information appearing in Storm Data originated from a source outside the National Weather Service (frequently credit is provided), Storm Data customers requiring additional information should contact that source directly. In most cases, NWS employees will not have the knowledge to respond to such requests. In cases of legal proceedings All actions that are authorized or sanctioned by law and instituted in a court or a tribunal for the acquisition of rights or the enforcement of remedies. , under Department of Commerce regulations and/or rules of the court, NWS employees are not legally obligated to provide written or verbal testimony.
1. A death resulting from an accident or disaster.
2. One that is killed as a result of such an occurrence. Codes: For events that include a fatality, there is a code containing the gender, age and fatality location at the end of the event narrative.

An "Episode" is an entire storm system and can contain many different types of events.
An "Event" is an individual type of storm event.
When listing wind speed values under "Character of Storm", ex. High Wind (G81), the G indicates a "Gust" which is a peak 5-second averaged wind speed in Knots (kts). 1 kt. = 1.152 mph. This number can be either E (estimated) by damage caused, or M (measured) by known calibrated anemometers. Ex. (M61) = measured 61 knots or E(75) = estimated at 75 knots.
All wind speeds listed are estimated by NWS personnel by the amount and type of damage unless otherwise noted with an "M" which represents an actual wind speed as measured by official NWS approved anemometer anemometer: see wind.
Instrument for measuring the speed of airflow. The most familiar instruments for measuring wind speeds are the revolving cups that drive an electric generator (useful range approximately 5–100 knots). .
When listing hail size under "Character of Storm", ex. Hail (2.25), the hail size is given in inches and hundredths of inches.
When listing property and crop damage, the figures indicated are the best guess made by the NWS from the available sources of information at the time of the printing.
The fatalities, injuries, and damage amounts appearing in tropical cyclone tropical cyclone
Severe atmospheric disturbance in tropical oceans. Tropical cyclones have very low atmospheric pressures in the calm, clear centre (the eye) of a circular structure of rain, cloud, and very high winds. events are attributed only to wind damage experienced in the coastal counties/parishes listed. Other tropical cyclone related events such as tornadoes and flooding are listed within their separate event types.
