Trinidad and Tobago Meteorological Service has issued Information Bulletin #2 advising citizens that the Inter-Tropical Convergence Zone (ITCZ) continues to remain active just east of Trinidad and Tobago as it is being influenced by a near- stationary, well- defined upper level trough. There is a 60% (medium) chance that there will be a change in the upper level trough position, resulting in an increase in rainfall over the next 18 to 24 hours.

Current analysis shows that Trinidad and Tobago can experience intermittent cloudy conditions, accompanied by periods of light to moderate showers or rain, some heavy at times, and the occasional thundershower mainly from tomorrow morning (Thursday 26th October, 2017).

Impacted areas which have recently experienced heavy flooding can expect faster than normal accumulation of water especially in saturated, flood prone and low lying areas. Respective Regional Corporations have been contacted and are aware of these existing levels of risk including, gusty winds, heavy showers or thundershowers and landslides in areas so prone.

The Office of Disaster Preparedness and Management (ODPM) will like to remind citizens of the following precautionary measures to prepare for incoming weather:

HOW TO OBTAIN SANDBAGS

Your Municipal Corporation will have sandbags ready to deploy at times of flooding and their priority is to protect the public at large. You should check with your own local Corporation for further information on acquiring sandbags and sand.

PROTECTING YOUR PROPERTY

Sandbags are of no use if your property is already flooded – concentrate your efforts on protecting yourself, your belongings and moving precious items out of harm’s way!

Consider all entry points that water could get through, not just doorways, such as airbricks, utility service point. Use other solutions for entry points where sandbags are not as effective.

You will need at least 6 sandbags to keep out 20cm depth of water for a standard door opening. Each sandbag will need approximately 15kg of sand. Citizens should use sharp, not soft, sand.

Filling the bags

This is a two person job: one to hold the bag open and one to fill.

· Do not fill bags more than half full.

· You don’t need to tie the end of the bag.

Placing the bags

· Clear any debris from the area where the bags are to be placed.

· If you can, put a large plastic sheet of heavy duty plastic between the sandbags and the wall of your house.

· Place the bags lengthways, tucking the open end under the filled half of the bag and position it pointing into the direction of water flow.

· Place bags in layers. Like a brick wall, make sure that in the next layer each bag overlaps the one below by half.

· Stamp bags firmly into place to eliminate gaps and create a tight seal by walking on it.

· To lay sandbags in a doorway, it may be necessary to empty some of the contents out or shape the sandbags to achieve a good fit without overlapping.

Additional waterproofing

Lay plastic sheeting across the side of the sandbag wall on the water side. Weigh down with additional sandbags.

The ODPM continues to work closely with the Regional Corporations’ Disaster Management Units to support ongoing relief activities, due to adverse weather conditions.
