  Notes on Advisories and Warnings
for Tropical Cyclones
 
    The information in this World Meteorological Organization (WMO) web site is based on advisories issued by Regional Specialized Meteorological Centres (RSMC), Tropical Cyclone Warning Centre (TCWC), and official warnings issued by National Meteorological and Hydrological Services (NMHSs) for their respective countries or regions.
 
    The advisories and warnings are issued by the respective RSMCs, TCWCs and the NMHSs in the Typhoon Committee region.
 
    Information presented in tropical cyclone advisories and warnings issued by the various centres may differ owing to differences in the availability of observational data, operational cutoff times, numerical weather prediction models as well as professional judgement.
