Global Tropical Cyclone and Disturbance Information
This page is updated every 15 minutes with the latest information on active storms and disturbances in all ocean basins from the
Automated Tropical Cyclone Forecast system (ATCF). Note: while this information is official, it is issued at 6-hourly intervals (0z, 6z, 12z, and 18z) which fall in between the normal NHC full advisory times (3z, 9z, 15z, and 21z). Thus, the two sets of information may differ. Visit the
National Hurricane Center or the
Joint Typhoon Warning Center for the latest official information.
There are currently no tropical cyclones in any ocean basin.
Invests
An invest is an area of disturbed weather for which the NHC is interested in collecting special data, such as microwave satellite imagery and specific model guidance. While the NHC says that designating a disturbance as an invest "does not correspond to any particular likelihood of development of the system into a tropical cyclone," it is generally known that if the NHC designates an invest, that system is of interest to them, and usually has at least a low chance of subtropical or tropical development. The ATCF file system contains specific information for active invests, similar to active tropical cyclones, and that information is displayed below, if available.
