All hurricanes are dangerous, but some more so than others.
The way storm surge, wind, and other factors combine determines the hurricane's destructive power. To make comparisons and descriptions easier, National Oceanic and Atmospheric Administration's hurricane forecasters use a disaster-potential scale which assigns storms to five categories on the basis of actual rotational wind speeds to estimate possible damage. 980 MB Storm surge generally 4-5 ft above normal. No real damage to building structures. Damage primarily to unanchored mobile homes, shrubbery, and trees.
