The map will show areas where inundation from storm surge could occur and how high above ground the water could reach in those areas. Gulf and East Coasts will be expanded to include Puerto Rico and the U.S. The potential storm surge flooding map issued by the National Hurricane Center that is currently produced for the U.S. Potential storm surge flooding map for Puerto Rico, Virgin Islands Livestreams will be broadcast at 11:30 a.m. The media pool is typically activated when a hurricane watch is issued for any portion of the U.S. Livestreams will be provided more frequently when the media pool is activated. The National Hurricane Center will experimentally provide simultaneous livestream broadcasts via its YouTube, Facebook and Twitter accounts when there is a system in the tropics that may pose a threat to land. National Hurricane Center to provide livestream broadcasts The size of each circle is set so that two-thirds of historical official forecast errors over the previous five years fall within the circles. The cone represents the probable track of the center of a tropical cyclone, and is formed by enclosing the area swept out by a set of imaginary circles placed along the forecast track at 12, 24, 36 hours, etc. The size of the tropical cyclone track forecast error cone for the Atlantic basin will be about the same as compared to 2022. Tropical storm, hurricane forecast cone will be about the same as 2022 To reduce the duplication of information and the opportunity for errors, the tropical cyclone watches and warnings will be removed from the tropical cyclone forecast/advisory. Before this year, a list of tropical cyclone watches and warnings were provided in both the forecast advisory and the public advisory. The National Hurricane Center is removing land-based tropical cyclone watches and warnings from the tropical cyclone forecast/advisory. Watches and warnings will be removed from the forecast advisory Intermediate advisories are issued at 2 a.m., 8 a.m., 2 p.m. The graphic will be made available about 15 minutes after the scheduled advisory release times, which remain at 5 a.m., 11 a.m., 5 p.m. East and Gulf coasts and in Puerto Rico and the U.S. Storm surge watches and warnings are currently issued in the Atlantic basin only for locations along the U.S. The graphic depicts peak storm surge forecast inundation values from the tropical cyclone advisory when storm-surge watches or warnings are in effect. While storm-surge graphics have been shown experimentally since 2020 on NHC's website, 2023 marks the first time they becomes fully operational. Here are the changes coming this year as announced by the National Hurricane Center. Saying goodbye to Ian, Fiona: Ian, Fiona retired from list of hurricane names because of 2022 death and destruction The Atlantic basin includes the Atlantic Ocean, Gulf of Mexico and the Caribbean Sea.Ģ023 hurricane predictions: AccuWeather issues 2023 hurricane season forecast, predicting 11-15 named storms The Hurricane Center begins issuing daily advisories May 15, although advisories are issued if something develops in the Atlantic basin. The Atlantic hurricane season runs from June 1 through Nov. The actual visual forecast "cone" provided by the NHC will not be extended yet. One of the biggest changes is extending the long-range forecast from the previous forecast of two and five days to two and seven days. The 2023 Atlantic hurricane season is coming faster than we like, and the National Hurricane Center is making a few changes. A previous version had made references to an extension of the forecast "cone," which is not being extended in 2023.
