Hurricane season begins June 1, but expert says people should prepare now An average year has 14 named storms, and seven hurricanes, including three major hurricanes. Colorado State University's prediction, which will be updated June 1, is for 13 named storms, six hurricanes, two of which will be major hurricanes of Category 3 or higher. With the potential of a hurricane-thwarting El Niño developing this summer, most seasonal forecasts have predicted slightly below to normal storm activity. “We are working with social scientists on what is the best way to display it.” “Some people don’t understand the cone, so two extra days may not help,” Cangialosi said. About one-third of the time, the center of the storm will travel outside the cone completely. Impacts such as storm surge and dangerous winds can occur far outside the cone. It is the most looked-at graphic, and often misunderstood.įor example, the cone only shows where the center of the storm may track. The forecast cone was first used in 2002 and is adjusted each year based on the error rates of the previous five hurricane seasons.
The hurricane center is working on a seven-day track forecast cone, but it is several years away. The track of a tropical cyclone, which can be a depression, tropical storm, or hurricane, is represented by the so-called cone of uncertainty. The NHC designates a budding disturbance as a tropical cyclone once it gains a closed center of circulation.
To be clear, the two-day and seven-day outlooks have nothing to do with the track forecast of a tropical cyclone once it forms. Seven-day hurricane forecast track cone of uncertainty in the works but years away “Although we were working with five-day timelines, the weather service works seven days in advance,” Cangialosi said. It was given a low chance of development five days before it was born as a subtropical storm, but meteorologists were fairly confident two days earlier that something was brewing.

Why this year's forecast comes with 'large uncertainty' "We've been doing it since 2018 internally." “It’s just about giving more lead time, giving people more time to watch it,” said John Cangialosi, a senior hurricane specialist at the NHC in Miami, who worked on the new forecast. While the seven-day advance warning may seem a minor tweak to the National Hurricane Center’s traditional tropical weather outlooks, which in the past have forecast two days and five days ahead, meteorologists hope adding two days to the timetable for potential landfall gives people more wiggle room to prepare, not panic. It's not a change to the iconic hurricane cone, which is a five-day track prediction used once a storm forms. The result of their research will debut this hurricane season in a forecast that shows the likelihood and location of storm formation seven days ahead of time.
