Hurricane Irma is forecast to bring hazardous sea and weather conditions to Cuba from around 7 September 2017. Expect high winds, heavy rain and storm surges. Monitor local media reports and follow the instructions of local emergency officials. Disruptions to essential services may occur. Contact your airline or tour operator to check if tourist services have been affected (see Additional information). Internet connectivity is very limited throughout Cuba. Do not rely on internet access for up-to-date information or as a way to alert friends or family to your situation in an emergency. The level of this advice has not changed. Exercise normal safety precautions in Cuba.
