Severe Weather Information Center (SWIC)

I’m occasionally asked for a source on tropical cyclone forecasts in ocean basins other than the Atlantic.  There is a World Meteorological Organization (WMO) web site, called the Severe Weather Information Center or SWIC, that was originally intended for the media to access basic information on current tropical cyclones issued by WMO Regional Specialized Meteorological Centers (RSMCs) and Tropical Cyclone Warning Centers (TCWCs) as well as official warnings issued by National Meteorological and Hydrological Services for their respective countries or regions.  21 WMO members are participating in SWIC.

http://severe.worldweather.org/ is developed and maintained by the Hong Kong Observatory.  Current tropical cyclones are plotted on the map found on the SWIC home page.  Today’s map, for example, displays Typhoon Mirinae which is currently approaching the Philippines.  Clicking on Mirinae shows the official forecast from RSMC Tokyo.

Given that different participating WMO members in some ocean basins may give different locations, intensities and even names for the same tropical cyclone, only the information supplied by the responsible RSMC or TCWC is displayed graphically on the maps to avoid confusion.
