Links to TC Sites

Official TC Sites
Hong Kong Observatory (HKO) Issues bulletins every 6, 3 or 1 hour(s) depending on the position of the TC.
Japan Meteorological Agency (JMA) TC-naming agency in NW Pacific. Issues bulletins every 3 hours.
Central Weather Administration (CWA) Issues bulletins every 6 hours (0, 6, 12, 18 UTC). Forecasts only positions but not intensities.
Joint Typhoon Warning Center (JTWC) A US Navy site. Issues bulletins every 6 hours (0, 6, 12, 18 UTC).
Korea Meteorological Administration (KMA) The official meteorological agency of Korea.
National Meteorological Center (NMC) The official meteorological agency of China.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) The official meteorological agency of the Philippines.
Other Sites with Current TC Information (Tracks / Advisories)
