NOAA's suite of sophisticated technologies – from next-generation models and satellite data to new and improved forecast and graphical products – enable decision makers and the general public to take action before, during, and after hurricanes, helping to build a more "Weather-Ready Nation." New tools available this year to assist in hurricane forecasts and communications include:
NOAA's fleet of earth-observing satellites is more robust than ever with the successful launch of the GOES-17 satellite in March. This satellite, along with the GOES-16 satellite – now GOES-East – contribute to a comprehensive picture of weather throughout the Western Hemisphere, allowing forecasters to observe storms as they develop.
The new polar-orbiting satellite, NOAA-20, will join the NOAA/NASA Suomi NPP satellite and use a suite of sophisticated instruments to gather high-resolution data from around the globe to feed NOAA's weather models, driving the 3-7 day weather forecast that is critical to preparedness and effective evacuations.
The National Weather Service will run a version of the Global Forecast System (called FV3 GFS) with a new dynamic core alongside the current GFS model – often referred to as the American model – during the 2018 season. This will mark the first dynamic core upgrade to NOAA's flagship weather model in more than 35 years, representing the first step in re-engineering NOAA's models to provide the best possible science-based predictions for the nation.
NOAA's hurricane-specific model – the Hurricane Weather Research and Forecast system – will be upgraded to offer greater resolution than ever before, increasing model resolution from 1.2 miles to 0.9 miles (2 km to 1.5 km) near the center of a storm. Additionally, the Hurricanes in a Multi-scale Ocean coupled Non-hydrostatic model was first implemented in 2017 and will undergo upgrades for the 2018 season to include greater resolution, new physics and coupling with ocean models.
NOAA's National Hurricane Center will make the Arrival Time of Tropical-Storm-Force Winds graphics operational for this hurricane season. One graphic displays the "earliest reasonable" arrival time of tropical-storm-force winds, at which point further preparedness activities could be hindered. A second graphic displays the "most-likely" arrival time of tropical-storm-force winds.
