Tracking the Tropics

MOUNT PLEASANT, S.C. (WCBD) – When Colorado State University published their original extended-range forecast for the Atlantic Hurricane season on April 2nd, the numbers were already expected to be above average.

CSU forecasted 16 named storms, 8 hurricanes, and 4 major hurricanes. The average numbers the Atlantic sees in a typical season are 12, 6, and 3, respectively.

On Tuesday, July 7th, Colorado State University updated its forecast for the Atlantic basin. They are now forecasting for 20 named storms, that’s an additional four more named storms than their previous prediction, and one additional hurricane, putting the number at nine.

The updated forecast is to include the five named storms we have already seen, Arthur, Bertha, Cristobol, Dolly, and Edouard. 

As far as the set up goes as we continue on into the Atlantic hurricane season, above-average sea surface temperatures are expected to continue. Weak La Nina conditions may evolve later in the summer months.
