1, Background
* The outline of hurricane Sandy
Hurricane Sandy was formed on October 22 and dissipated on October 31. Its highest winds throughout all the date was 110mph (175km/h) and the lowest pressure was 940hPa. The number of fatalities was 253 in all, and all costs of damage, at least, have risen to $65.6 billion. Affected areas by this hurricane expanded to wide range.
