If Hurricane Opal makes landfall as a Category 3 storm, how many square miles of the Pensacola area will be flooded. Use the maps produced by the Escambia County Emergency Management Services. Understand that a Category 3 storm will also flood the same areas as a Category 1 and 2 storm. The scale for the downloaded individual maps are located on each map. Make sure the individual maps are downloaded into a separate folder, to be analyzed individually. Be aware of areas on some of the maps which overlap from one image to another. Do not count them twice. An approximation of the over lapped area is fine. 2. If the average population density in map area 5 (Western Escambia County - Zones 1, 2, 3, 4, 5, 6, 7, 20, 21, 22) is 1500 (estimate) people per square mile, how many individuals must be evacuated? 3. Tropical force winds from the hurricane reach 125 miles from the eye with hurricane force winds reaching 75 miles from the eye. Automobiles will be blown off the road in tropical force winds. By what time must everyone be evacuated and in shelters to be safe? If individuals have not evacuated by this time, then they must (or should we say should) remain in their homes. 4. Due to limited evacuation routes (Pensacola Area Road Maps), the roads may only be able to handle 850 (estimate) cars per hour. If the cars contain an average of 3 people, at what time must people begin evacuating in order to reach a designated shelter established by the County's EMS system? These individuals must be in shelters at least thirty minutes prior to the effects of tropical force winds.
