Outflow boundary on radar with radial velocity and frontal boundary drawn in.. An outflow boundary, also known as a gust front, is a storm-scale or mesoscale boundary separating thunderstorm-cooled air from the surrounding air; similar in effect to a cold front, with passage marked by a wind shift and usually a drop in temperature and a related pressure jump.
Monday's gust was the highest daily peak gust in almost six years, since the observatory measured a 171-mph gust on Feb. 25, 2019, reported the observatory, a private nonprofit research institution.
A prognostic chart is a map displaying the likely weather forecast for a future time. Such charts generated by atmospheric models as output from numerical weather prediction and contain a variety of information such as temperature , wind , precipitation and weather fronts .
The wind speeds must not be directly associated with a tropical cyclone. Wind advisory NPW – Strong sustained winds of 31 to 39 miles per hour (50 to 63 km/h) for one hour or longer and/or wind gusts of 46 to 57 miles per hour (74 to 92 km/h) for any duration are expected within the next 12 to 24 hours. Wind speeds may pose a hazard to ...
A slight risk day typically will indicate that the threat exists for scattered severe weather, including scattered wind damage (produced by straight-line sustained winds and/or gusts of 60 to 70 mph), scattered severe hail (varying in size from 0.25 inches (0.64 cm) to 1.75 inches (4.4 cm)) and/or isolated tornadoes (often of shorter duration ...
Maps show the areas impacted by storm surge, rainfall levels and more as Helene, once a major hurricane and now a tropical storm, moves inland from Florida's Gulf Coast over Georgia.
The Global Wind Atlas is a web-based application developed to help policymakers and investors identify potential high-wind areas for wind power generation virtually anywhere in the world, and perform preliminary calculations. It provides free access to data on wind power density and wind speed at multiple heights using the latest historical ...
