Isolated strong to severe thunderstorms will be possible across parts of the Southern Plains into the lower Mississippi Valley. Locally heavy rain will impact the central Gulf Coast. Another Pacific storm will produce moderate to heavy precipitation amounts into northern California and southwestern Oregon. Michael Brennan, Ph. Brennan served as a senior hurricane specialist at NHC from to , a position where operational duties include the issuance of track, intensity, and wind radii forecasts and associated watches and warnings for tropical cyclones in the Atlantic and eastern North Pacific oceans. He also conducts training on a variety of topics related to tropical cyclones and as well as National Hurricane Center products, including forecast uncertainty and messaging.

Storm Surge Watches and Warnings are not issued for southern California. Any departure in the forecast from the actual track, size, or intensity of a hurricane can dramatically change its impacts. Through the implicit use of probability data, color-coded HTI graphics depict the potential conditions to protect against with accompanying descriptions of potential impacts needed for effective preparations. The HTI graphics account for the latest forecast at specific locations while also including a reasonable safety margin to account for any forecast errors. What hazards are described by the HTI Graphics? Tropical wind, storm surge, flooding rain, and tornadoes are the hazards addressed within the HTI graphics suite. Since the Cone Graphic only reveals the most probable track of the center of the storm, it provides little to no information about projected impacts. The HTI graphics, however, show the geographic extent of associated hazards; their level of threat and potential impacts. Impacts often extend well-beyond the area depicted in the Cone Graphic alone. The HTI color-scale corresponds to increasing levels of threat and is graduated from warm to hot colors. Examining the wind graphic above; left , locations colored in purple have the potential to experience winds greater than mph when accounting for both the forecast and forecast error. It is not a mere depiction of forecast conditions to be expected. Rather, it indicates that these locations should be ready for winds in excess of mph, when taking into account the latest forecast and knowing that although skilled the forecast isn't perfect. Simply put, locations in purple are being threatened by major hurricane force winds greater than mph at least Category 3 force , locations in red are being threatened by hurricane force winds between mph Category 1 or 2 force , and so on.

The Technology and Science Branch TSB provides technical support for the center, which includes new infusions of technology from abroad. The Chief, Aerial Reconnaissance Coordination, All Hurricanes CARCAH unit tasks planes, for research and operational purposes, to tropical cyclones during the Atlantic hurricane season and significant weather events, including snow storms, during winter and spring. During the Atlantic and northeast Pacific hurricane seasons, the Hurricane Specialist Unit HSU issues routine tropical weather outlooks for the northeast Pacific and northern Atlantic oceans. When tropical storm or hurricane conditions are expected within 48 hours, the center issues watches and warnings via the news media and National Oceanic and Atmospheric Administration NOAA Weather Radio. Although the NHC is an agency of the United States, the World Meteorological Organization has designated it as the Regional Specialized Meteorological Center for the North Atlantic and eastern Pacific, making it the clearinghouse for tropical cyclone forecasts and observations occurring in these areas. If the NHC loses power or becomes incapacitated, the Central Pacific Hurricane Center backs tropical cyclone advisories and tropical weather outlooks for the northeast Pacific Ocean while the Weather Prediction Center backs up tropical cyclone advisories and tropical weather outlooks for the North Atlantic Ocean. After his death, hurricane warning services were assumed by the United States Signal Corps and United States Weather Bureau over the next decade, first based in Jamaica in and Cuba in before shifting to Washington, D.

This responsibility passed to regional hurricane offices in , and the concept of the Atlantic hurricane season was established to keep a vigilant lookout for tropical cyclones during certain times of the year. Hurricane advisories issued every six hours by the regional hurricane offices began at this time.
