Tropical Storm 39–73 0–3
Tropical Depression 0–38 0
The Saffir-Simpson Hurricane Scale is a classification used for most Western Hemisphere tropical cyclones that exceed the intensities of "tropical depressions" and "tropical storms", and thereby become hurricanes. Source: Intellicast

NOAA 48-hr TC Formation Probability

Tropical Cyclone Formation Chances Within 48 Hours
The NOAA forecast/image above uses NCEP global forecasts, Reynolds weekly sea surface temperature, and GOES-East, GOES-West, MTSAT-1R and Meteosat-7 channel-3 (water vapor) imagery are used as input to an algorithm to estimate the probability of tropical cyclone formation within 500km of each grid point within the next 48 hours 45 S to 45 N and 0 to 360 E.
