Rome, June 20 - Summer is giving Italians an overly warm embrace as hot muggy weather on Thursday continued to prevail across most of the country. Temperatures simmered in the mid-30s (degrees celsius) particularly in the centre and south, but also in northeastern Italy on the border of Austria, sparking health warnings in many areas of the peninsula. The humid heat wave hitting central Italy, brought on by the weather system 'Ada', prompted authorities in the port city Pescara to call a level-three health-alert, meaning that healthy, active people were at risk as well as vulnerable categories like the elderly, small children and chronically ill. The perceived temperature in Pescara is expected to reach 36C on Thursday. Meanwhile, temperatures in the region of Puglia - the heel of Italy's boot - are could touch 38 degrees celsius. But storms are bringing relief at least to northwestern Italy, knocking temperatures down to well under 30 degrees in cities like Turin, Milan and Genoa. No rain is forecast in the coming days for southern Italy, but thunder-showers are expected Monday in the eastern parts of north and central Italy.
