The Weather Prediction Center also acts as the backup office to the National Hurricane Center in the event of a complete communications failure. Long range climatological forecasts are produced by the Climate Prediction Center (CPC), a branch of the National Weather Service. These include 8–14 day outlooks, monthly outlooks, and seasonal ...
The Weather Prediction Center in College Park, Maryland provides guidance for future precipitation amounts and areas where excessive rainfall is likely, [34] while local NWS offices are responsible for issuing Flood Watches, Flash Flood Watches, Flood Warnings, Flash Flood Warnings, and Flood Advisories for their local County Warning Area, as ...
During El Niño events, precipitation averages about 10 percent above normal, while La Niña events lead to precipitation amounts which average close to 10 percent below normal. [79] Pago Pago harbor in American Samoa has the highest annual rainfall of any harbor in the world. [80] This is due to the nearby Rainmaker Mountain. [80]
The quantitative precipitation forecast (abbreviated QPF) is the expected amount of melted precipitation accumulated over a specified time period over a specified area. [1] A QPF will be created when precipitation amounts reaching a minimum threshold are expected during the forecast's valid period. Valid periods of precipitation forecasts are ...
The forecast is similar for Hendersonville, with an 80% chance of rain Thursday night and Friday. The NWS's model guidance projects for the storm to move out of WNC by the end of the day Friday or ...
The launch of GOES-N, which was renamed GOES-13 after attaining orbit. The Geostationary Operational Environmental Satellite (GOES), operated by the United States' National Oceanic and Atmospheric Administration (NOAA)'s National Environmental Satellite, Data, and Information Service division, supports weather forecasting, severe storm tracking, and meteorology research.
Rain. AccuWeather meteorologists are forecasting a widespread 4-8 inches of rainfall across the Florida Panhandle and Big Bend Region through Saturday, with a zone of 8-12 inches of rain possible ...
Numerical weather prediction (NWP) uses mathematical models of the atmosphere and oceans to predict the weather based on current weather conditions. Though first attempted in the 1920s, it was not until the advent of computer simulation in the 1950s that numerical weather predictions produced realistic results.
