Data Layer:
Wind Risk Zones
Content:
 Relative risk from wind damage
Relative risk areas from high speed wind gusts
Use Notes:

Wind Zones correlate to "design specifications of a shelter or safe room" based on wind speeds with a 3-second gust.

Zone 1 = 130 mph
Zone 2 = 160 mph
Zone 3 = 200 mph
Zone 4 = 260 mph

For purposes of determining home shelter needs, please use this map in conjunction with Wind Risk Zones and the associated risk chart. Click source below and/or overlay both data layers on Map Viewer.
