(ANSA) - Rome, August 16 - Another heat wave, the seventh, is about to hit Europe, sending temperatures to new record highs. According to 3bmeteo.com, the "Desert Colossus", will strike Europe between August 18 and 21, sending temperatures up to a sweltering 40 degrees celsius or higher in France and Spain and reaching as far north as Lapland. In Italy the regions most likely to feel scorching heat are Lombardy, Emilia, Tuscany, Lazio and Sardinia. The successive heat waves of this summer, coming as Italy is suffering its worst drought in 10 years, have already left their mark on the country's economy: some one billion euros in agriculture damage alone. The upcoming grape harvest is expected to suffer the steepest decline in volume in a century, though quality will be high, according to a report published Tuesday by Italian farming association Coldiretti.
