Tourists in central Athens huddled under mist machines, and zoo animals in Madrid were fed fruit popsicles and chunks of frozen food, as southern Europeans braced for a heat wave Thursday, with a warning of severe conditions coming from the European Union’s space agency.

Emergency measures – including staffing changes, cellphone alerts, and intensified forest fire patrols – were readied or put into effect in several countries as temperatures in parts of Mediterranean Europe were set to reach 45 degrees Celsius (113F) Friday and into the weekend.

Working hours were changed

In Athens and other Greek cities, working hours were changed for the public sector and many businesses to avoid the midday heat, while air-conditioned areas were opened to the public.
