    TROPICAL CYCLONE ADVICE NUMBER 001Issued at 09:55 am on Monday, December 11, 2006BY Anonymous

    A SEVERE CATEGORY 4 CYCLONE is now current for AMPARA and MATARA District coastal areas. At 06:00 am local time SEVERE TROPICAL CYCLONE MONTY was estimated to be 80 kilometres northeast of Ampara District and moving southwest at 10 kilometres per hour. Severe Tropical Cyclone Monty is expected to cross the coast in the vicinity of Ampara and Matara Districts during Monday. Gales with gusts to 180 kilometres per hour are likely in coastal communities in Ampara and Matara District during the day.

    This is to alert the residents of Ampara and Matara District about the potential of a very dangerous storm tide as the cyclone centre approaches the coast. Tides are likely to rise significantly above the normal high tide mark with very dangerous flooding, damaging waves and strong currents.

    Widespread heavy rain and further flooding are likely in southern parts of the Ampara and Matara Districts over the next few days.
