Hurricane and emergency preparedness planning, risk evaluation and action steps that will be taken are each part of a process that evolves as a known weather event develops and moves closer to landfall.
For 2021, Colorado State university (CSU) hurricane researchers are predicting an above-average Atlantic hurricane season, which typically runs from June 1 to November 30 each year. Specifically, CSU researchers believe there will be 17 named storms in 2021. This estimate is above the average 12.1 named storms per year that occurred from 1981-2010.
Of the predicted 17 named storms, eight are expected to become hurricanes and four could reach major hurricane strength with sustained winds of 111 miles per hour of more. These predictions are based on statistical models that use 40 years of historical hurricane season data and evaluate conditions like Atlantic sea surface temperature, sea level pressures, vertical wind shear levels and other factors.
