 The Saint Lucia Med Services has advised that a strong tropical wave will be passing through the south of Saint Lucia Wednesday evening into Thursday. Though the system may pass near the south, we are expecting that the northern portion will also be equally affected as the south. We are expecting heavy showers, rainfall and thunderstorms. Persons who live in low-lying areas, you are asked to be cautious and to be vigilant because we are expecting flash flooding and there is also the possibility of land slippage. Motorists who are traversing from the north to the south, south to the west via any of the roads whether it's east coast or west coast, we are asking you to be very careful as there may be the possibility of rockfall. As the system progresses, the Saint Lucia Med Services and NEMO will be keeping the public updated as to the weather system and its progress. We ask that persons continue to be vigilant and also as always monitor the official sources of information.
