Abstract: When a hurricane evacuation is halted, large numbers of motorists may be stranded without official shelter. Multilevel aboveground parking garages may be feasible |Refuges of Last Resort| (RLR). Our goal was to assess the relative safety of using a parking garage as an RLR through fieldwork on the wind patterns inside a parking garage during hurricane Isabel. Mean wind speed inside the second floor of the garage, 6 m (20 ft) from upwind openings, was 26% of the outdoor mean. Gusts averaged 33% of outdoor gusts. Wind measurements on the second floor of the garage showed that gusts inside the garage were 10% to 30% of outdoor gusts. These results were supported by testing a model parking garage in a wind tunnel. Motorists inside a vehicle using a parking garage as a |refuge of last resort| during a hurricane are relatively safe with respect to wind.
