This year wm ann. <br />above average year for the Atlantic Region Our activity a was record breaking year for the <br />strength of hurricanes, This year five (5) major hurricanes developed in the Atlantic Region, <br />hurricanes fret, Ondy, Floyd, Gert, and Lenny all became Category Ill c+r stronget with <br />I im-ricanc Floyd being the strongest with sustained winds of 155mph. No Category V <br />hwricanes developed in the Atlantic Region during the 1949 season An unusual part of the <br />season was the lack ofat'tivity in the Eastern Pacific Ocean Only rune fol named systems <br />in the Eastern Pacific and five (S) depressions which could not orgaatce. This reinforced the <br />presence of the La Nina phenomenon which tends to increase Atlantic Region activity and <br />decrease Pacific activity due to cooler ocean walcrs. <br />Along with the number of major hurricanes, landfalls of tropical systems were above normal. <br />A total of eleven f 11) systems made landfall somewhere in the Atlantic Region. In the <br />I:astern Pacific Region only one (1) tropical storm moved over land. Of the Iandtalls in the <br />Atlantic Region, hurricane Floyd was most definitely the cosrJiewt hurricane with damages <br />totaling over $6 Billion. f luiricanc Lenny was the most unusual landfalling because of the <br />direction of movement and lire time of year. Lcnny bccanic a Category I V hurricane and <br />moved cast through the Caribbean in lair November Total approximate economic damage <br />for this Year is $8 Billion, <br />lndinei River County fully activated the Fmerpency Operalimris Center one lime artd I'artiall;• <br />activated the EDC two tithes. The ECIC was fully activated for ata hours during Hurricane <br />Floyd. I lutricane Floyd was the largest system this year with a 600 mile diameter as it was <br />400 miles east of Florida. Evacuations were ordered and shelters were opened throughout <br />the county. The center of Floyd did not make landfall over Indian River County but, the <br />county did experience sustained winds or 70mph in some areas. The EDC was partialiv <br />activated for Hurricane Dennis as it moved passed l-lorida. Atone tinoc the system appeared <br />to threaten Florida and Hurricane Watches were issned for our area Ilia. ren effects were <br />experienced from Dennis. Fuially, the EDC was partially activated for Hurricane Irene. <br />Irene was the costliest system for Indian River County. The system made landfall with <br />weaker winds than Floyd but, almost 20 inches of rain. This rain produced flooding <br />
