2020 Atlantic Hurricane Forecast

The 2020 extended range tropical forecast has been published by Colorado State University Department of Atmospheric Science.

As at April 2, the forecast is for above average activity for the Atlantic Ocean basin. Sea surface temperatures averaged across the tropical Atlantic are somewhat above normal and potentially expect weak La Niña conditions by this summer or fall.

The forecast predicts an above average probability for major hurricanes making landfall along the continental United States coastline and in the Caribbean.

2018 Atlantic Hurricane Season Forecast

The 2018 extended range tropical forecast has been released updated by Colorado State University Department of Atmospheric Science.

As at April 5 July 2, the forecast is for slightly above average storm activity below average activity for the Atlantic Ocean basin. The current weak La Niña is not expected to transition into a significant El Niño by summer and fall. El Niño conditions create vertical wind shear that inhibits hurricane formation. Without wind shear, the tropical Atlantic is conducive to storm development.

We have decreased our forecast and now believe that 2018 will have below-average activity. The tropical and subtropical Atlantic is currently much colder than normal, and the odds of a weak El Niño developing in the next several months have increased. With the decrease in our forecast, the probability for major hurricanes making landfall along the United States coastline and in the Caribbean has decreased as well.

The forecast predicts a slightly above-average below average probability for major hurricanes making landfall along the continental United States coastline and in the Caribbean.
