As strong winds and heavy rains swept across the country yesterday, Athens proved once again to be incapable of weathering a storm successfully. Streets such as the Kallirois Avenue underpass at the Syngrou Avenue intersection were blocked by floodwaters, causing monumental traffic jams that lasted for hours. Traffic lights were also knocked out. The fire brigade had to help at least 200 people whose homes or shops had been flooded. Traffic was also affected by floodwaters on the old and new Athens-Corinth highways. Fortunately, the Kifissos River, which had swelled with the rain, did not break its banks as it did several times last year. The strong winds, reaching up to 10 on the Beaufort scale, forced ferries to remain in port. Today, winds of up to 9 on the Beaufort scale are expected. Tomorrow, Christmas, will see snow falling in the mountains, with rain elsewhere, including Athens. The weather is expected to improve as of Friday.
