Information Bulletin # 2

Tuesday 20th June, 2017 – 8:00 p.m.


TTMET issues Riverine Flood Bulletin #2


The Trinidad and Tobago Meteorological Service is continuing the riverine flood alert for Trinidad. Riverine Flooding is more prolonged and widespread in comparison to street and flash flooding.


Data from the Water Resources Agency indicate that some of the nation’s major rivers have over spilled and others are approaching threshold levels. Minor rivers and tributaries have already burst their banks. Water levels continue to rise in the primary Caroni river and is threateningly high.


Runoffs from the recent rainfall activity over the last 6 – 12 hours would definitely increase the chance of the major rivers reaching critical levels.


The Office of Disaster Preparedness and Management (ODPM) advises citizens, specifically those residing in the Caroni River Basin to be on the alert for rising river levels and possible overspill. All necessary measures MUST be taken to preserve life and property.




The ODPM reminds all citizens that if they have been affected by this inclement weather, to please contact our Customer Care Centre at 511, 999 or 211.


Consequently, the ODPM will like you to protect 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 harms 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 won’t be effective.


You’ll 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. You 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, place a large 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


Sandbags are popular but they have disadvantages:


  • During an emergency sufficient quantities may be difficult to obtain.

  • They are time consuming and require two people to fill.

  • They can be difficult to handle, particularly for the elderly or infirm.

  • When they come into contact with floodwater they tend to retain contaminants such as sewage.

  • Sacking material is biodegradable, and will disintegrate if left in place for long periods of time.







The ODPM as the lead National Office for Disaster Management is coordinating with all relevant agencies, including the Regional Corporations’ Disaster Management Units and the Tobago Emergency Management Agency to prepare for the possibility of localized rainfall within the next 5-8 hours, as we continue to closely monitor this situation through the TTMET Office. The ODPM reminds all citizens to dispel any social media rumours and obtain advisories from authorised messages from the TTMET Office and the ODPM through local media houses’ updates.
