"ATHENS, Greece (CNN) -- The capital of Greece appeared safe from wildfires that have raged for days, firefighters said Monday, but they remained on standby in anticipation of flare-ups caused by strong winds. Firefighters scrambled Monday to exploit a lull in gale-force winds that had hampered firefighting efforts over the weekend. But despite the calmer weather, some strong gusts of wind Monday morning grounded four water-dropping flights, officials said. Mondays winds flamed new fires farther southeast of Athens, in the cities of Pikermi and Kallitechnoupolis. And a dozen nuns were rescued from outside of Athens when flames engulfed their convent in Nea Makri, officials said. At least 90 wildfires have burned since Friday, devouring hundreds of homes and 15,000 hectares. About six major fires still raged throughout the country Monday. Are you there? Send us your pictures"
