  • Tropical cyclone WILLA continued toward the coast of southern Mexico, strengthening. On 23 October at 3.00 UTC its centre was located approx. 125 km south-west of the Islas Marias (Nayarit State) and 310 km south-south-west of Mazatlán town (Sinaloa State), with maximum sustained winds of 231 km/h (equivalent to a Category 4 hurricane). On 21 October, the Global Disasters Alerts and Coordination System (GDACS) issued a RED alert for WILLA for 23 October.

  • WILLA is forecast to pass over the Islas Marias as an intense major hurricane, before making landfall between Mazatlán (Sinaloa State) and San Blas (Nayarit) on 23 October evening as a Category 2 hurricane. It will weaken to a tropical depression as it moves inland on 24 October.

  • Meanwhile, tropical cyclone VICENTE continued west-north-west along the coast of southern Mexico, as a tropical storm. On 23 October at 3.00 UTC its centre was located approx. 220 km south-east of the coast of Michoacán State, with maximum sustained winds of 65 km/h.

  • VICENTE is forecast to make landfall as a tropical depression on 23 October afternoon - at the same time as WILLA - over the coast of Michoacán State, approx. 590 km south-east of WILLA's projected landfall.

  • Very strong winds, heavy rainfall and storm surge could affect several areas of south-western, central and north-eastern Mexico, especially Nayarit (including Islas Marias), Jalisco and Sinaloa States on 23-24 October. Around five million people could be exposed to heavy rain and winds, and over 100 000 could be directly affected.
