Uncommon atmospheric circumstances spawned a pair of tropical cyclones in the western Pacific—one on either side the equator, at nearly the same longitude, at nearly the same time. Why are twin cyclones more common during El Niño?
More than halfway through August, the Atlantic Ocean has seen just two named storms. Despite the availability of heat energy at the sea's surface, atmospheric conditions have not been favorable for storm development.
This guide from NOAA's Coastal Service Center provides links to resources for managing the impacts of hurricanes and tropical storms, and helps users locate data to use before, during, and after a storm. The site also highlights geographic information system (GIS) data layers useful for planners and emergency responders.
