Less Tropical Development than Usual Expected for 2026 – New Tech Provides More Accurate Forecasts

by Kerri Cooke

As we enter hurricane season, communities across the Gulf Coast and Eastern Seaboard can feel uneasy.

Humans hate the unpredictable, and there’s not much predictability when it comes to the specifics on what will happen during hurricane season. For the last few years, we were warned of a bad season, only for there to be less storms to impact the United States, but it only takes one to devastate entire communities. Still, hurricane forecasts have their place. They take into account environmental conditions expected during the summer months which can hinder or help hurricane development.  

Both reputable hurricane forecasters at Colorado State University (CSU) and the National Oceanic and Atmospheric Administration (NOAA) call for a lower-than-average season. CSU’s prediction is 13 named storms, six hurricanes and two major hurricanes, while NOAA, which has the most updated forecast considering environmental conditions, expects between eight to 14 named storms, three to six hurricanes and one to three major hurricanes. Both forecasts expect generally the same amount of activity. 

The questions are when the weather pattern flips to El Niño from its current neutral pattern, how soon this occurs, how strong El Niño becomes and how warm ocean temperatures are. El Niño favors less tropical activity in our area of the world due to wind shear but the effects will be opposite for those along the Pacific Ocean. Meanwhile, ocean temperatures are warmer than normal in parts of the Atlantic Ocean, so it’s undetermined how much of an impact that will have on development despite an El Niño pattern. Another unknown in the forecast is the strength of El Niño. There are some predictions that a super El Niño event could form during hurricane season’s busiest months and last throughout the winter. 

There are some changes and technological advancements to be implemented this year that will make hurricane forecasting more accurate. The cone of uncertainty is upgraded with warnings reaching inland areas and not just first landfall coastal area. For example, during Hurricane Laura, the storm left major destruction from the Louisiana coast into Arkansas. Similar potential for effects inland will now appear in watches and warnings. In addition, tropical waves with little expectation of development will now feature on maps as a gray X instead of a yellow one. 

Another interesting new development in forecasts this year is NOAA’S incorporation of data from Black Swift Technologies’ S0, a drone that will be deployed from the hurricane hunter plane. The drone will be able to get closer to the surface of the water to measure factors such as atmospheric pressure, temperature, wind and humidity levels. With the use of this new data, forecasts are expected to be anywhere from 10-25% more accurate. 

As always, stay weather aware despite this blanket forecast. What is most important is to stay tuned to regular tropical updates and warnings. There is no guarantee there won’t be a hurricane along the Gulf Coast this year—only the determination that storms will have more trouble forming.
