From the Summary: "Timely tropical cyclone forecasts can provide early and accurate warnings to parts of the U.S. coastline vulnerable to tropical cyclone impacts. The National Oceanic and Atmospheric Administration (NOAA) is the federal agency responsible for tropical cyclone forecasts, including track, intensity, storm surge, and rainfall forecasts. NOAA defines 'tropical cyclones' as tropical depressions, tropical storms, hurricanes, and major hurricanes, and the agency makes tropical cyclone forecasts using data from multiple observational tools-- satellites, reconnaissance aircraft, ships, radar, and buoys, among others. Each year, NOAA releases outlooks for three ocean regions--Atlantic, eastern Pacific, and central Pacific. Although the outlooks typically cover all types of tropical cyclones, the agency uses the term 'hurricane' in the outlook title. The north Atlantic and eastern Pacific outlooks include the predicted number of named storms (typically tropical storm strength or stronger), hurricanes, and major hurricanes. The central Pacific outlook forecasts the total number of tropical cyclones expected. NOAA released its 2020 hurricane season outlooks for the Atlantic, eastern Pacific, and central Pacific regions in May 2020. NOAA predicts an above-normal season in the Atlantic, with 13 to 19 named storms, 6 to 10 hurricanes, and 3 to 6 major hurricanes."
