NOAA is updating its definition of what a "normal" Atlantic hurricane season looks like, based on the last 30 years. The average number of hurricanes in the new normal has risen from 6 to 7.

In May, NOAA will release its once-a-decade update for the 30-year weather averages that local meteorologists use. In many places, it will mean far fewer days that are "above normal."
