New hurricane categories? Hurricanes are graded on the Saffir-Simpson scale, which ranges from Category 1 (starting at sustained winds of 74 mph, or 119 km/hour winds) to a Category 5 (starting at sustained winds of 157 mph, or 252 km/hour winds). This scale is incomplete, as it is ...

The Saffir-Simpson Hurricane Wind Scale places hurricanes into one of five categories according to their sustained wind speeds at a given time. It also offers estimates of the damage typically associated with such storms. In general, each increase in Saffir-Simpson category translates into a fourfol...
Every fantasy basketball league is different. While there are basic rules and settings that apply across the board (you will learn about those below), each league takes on its own identity based on settings like roster size, injury spots, stat categories and other specifics. ...

Hurricanes are tropical storms that form over the warmer oceans near the equator and include wind speeds from 74 miles per hour to over 200 miles per hour. Five wind-speed-based categories of NOAA hurricanes exist, with a category 5 storm having winds ex
