the majority of the winter crops are lost. The lowest <br />temperature ever recorded in the state of Florida is -2°F <br />(NCDC, 1999a) on February 13, 1899 in Tallahassee. Since <br />December 1889, there have been at least 22 recorded severe <br />freezes; the most recent being in 2010, when a Secretarial <br />Disaster Declaration was issued for crop losses estimated to <br />be in the hundreds of millions of dollars. During this event, <br />everything from fruits and vegetables to nursery plants and <br />shrubs to tropical fish felt the effects of the freeze. There were <br />no data available to document previous occurrences of severe <br />freeze by jurisdiction. <br />During the 2013 revision process, data indicated that the <br />likelihood and probability of future occurrences of severe <br />winter storms in Florida tended to result more in flooding and <br />tornadoes than in snow and ice. Based on all the historical <br />evidence, it is anticipated that a moderate freeze may be <br />expected in Florida every one to two years. Severe freezes, <br />where the greatest numbers of winter crops are lost, may be <br />expected on average once every five years based on historic <br />FEMA -declared disasters. <br />Extent. The minimum temperature recorded in the Vero <br />Beach area was 25 degrees (19 degree wind chill) on <br />12/14/10. This could be considered the minimum likely <br />temperature to be experienced in the Vero Beach area. <br />Probability. Severe winter weather includes extreme cold, <br />snowfall, ice storms, and/or strong winds, and can affect every <br />state in the United States in some fashion. Areas where this <br />weather is uncommon, such as Florida, are typically more <br />affected by winter weather than regions that experience this <br />more frequently. Agriculture is the state's primary vulnerability <br />to this hazard since freezing temperatures can kill or damage <br />winter crops. Significant economic impacts in Florida led the <br />NCDC to maintain freeze and frost data throughout the state. <br />The probability of winter storms and freezes for Indian River <br />County is low considering the entire state of Florida maintains <br />a five percent probability or higher of a freeze or frost annually, <br />all of which are located in the upper half of Florida. <br />g.
