The National Hurricane Center and Central Pacific Hurricane Center maintain schedules and products designed to inform the public when a tropical storm watch or warning is issued and when conditions may threaten coastlines. The NHC issues tropical cyclone advisory products at least every six hours at 5 AM, 11 AM, 5 PM, and 11 PM Eastern daylight time. The CPHC follows a parallel schedule at 5 AM, 11 AM, 5 PM, and 11 PM Hawaii standard time.
When coastal tropical storm or hurricane watches or warnings are in effect, the centers issue Tropical Cyclone Public Advisories every three hours. Those public advisories list all active coastal watches and warnings, the cyclone position, maximum sustained winds, motion, and a description of associated hazards. The advisories are available on hurricanes.gov and weather.gov slash cphc. They also reach the public through television, radio, cell phones, and NOAA Weather Radio.
The National Weather Service emphasizes that storm surge and wind products carry specific time horizons and actions. A Storm Surge Warning signals life threatening inundation from rising water somewhere within the warning area, generally within thirty six hours, and the public should check for evacuation orders. A Hurricane Warning means sustained winds of seventy four miles per hour or greater are expected somewhere within the warning area. The NHC issues that warning thirty six hours before tropical storm force winds are anticipated to give people time to finish preparations.
The NWS explains that watches give more lead time. A Storm Surge Watch signals the possibility of life threatening inundation generally within forty eight hours. A Hurricane Watch means hurricane conditions are possible within forty eight hours and a Tropical Storm Watch covers possible tropical storm conditions within the same period. The agency also warns that NWS may issue these watches and warnings for disturbances not yet meeting all tropical cyclone characteristics. Those systems may be called potential tropical cyclones. Warnings may also apply to post tropical cyclones that still pose danger.
Outlooks, Local Products, And Forecast Risk Services
The Tropical Weather Outlook provides a discussion of disturbed weather and its potential for development during the next five days. The Outlook gives categorical probabilities of formation during the first forty eight hours and for the entire five day period. Graphical two day and five day outlooks appear on hurricanes.gov and weather.gov slash cphc to help planners see where systems may form or move.
Local NWS forecast offices issue Hurricane Local Statements to summarize potential storm impacts and preparedness information for their areas of responsibility. Those statements present expected impacts ordered by greatest risk and may include sections on wind, storm surge, inland flooding from heavy rain, tornadoes, and other coastal hazards. The offices also produce Tropical Cyclone Threats and Impact Graphics showing threat assessments for wind, coastal flooding, inland flooding, and tornadoes.
Outside government forecasts, Tropical Storm Risk delivered by EuroTempest offers long range forecasts and event based spatial datasets for users that include insurers and maritime interests. TSR reports current activity and risk. As reported by TSR there were five active tropical cyclone systems as of 8 Oct, 2026 15 59 GMT. Agencies and the public are directed to official NHC and CPHC products for watches and warnings, and to local NWS offices for detailed local impact information.
