Improvements for 2018 hurricane season
Published on April 17th, 2018
The National Hurricane Center plans to shrink the dreaded “cone of uncertainty” during the upcoming season based on an improving forecast record. The Miami-based center announced a series of other changes intended to improve how hurricane forecasters convey warnings to the public.
Along with the shrinking cone, forecasters will extend advisories, which include warnings and watches, to 72 hours in advance of a storm, providing a full additional day to prepare. Experimental graphics used last year to depict arrival times for dangerous winds will also become a permanent addition to forecasts.
“The changes are to improve information contained in the hurricane center products and to provide it in maybe easier to understand formats,” said Dan Brown, a senior hurricane specialist in charge of warning coordination.
The forecast cone has long been a fixture of the hurricane forecasts but frequently debated because the public tends to focus on the center track, ignoring dangerous winds and other hazards that can extend for many more miles.
