Dominica Floods Demonstrate Need for Improved Early Warning System

Last week the UN said that the recent disaster in Dominica highlighted the need for improved early warning systems for small island states facing increasing threats from a changing climate.

In a statement made on 04 September, Margareta Wahlström, head of the UN Office for Disaster Risk Reduction (UNISDR), extended her condolences to the people of the small island state of Dominica during a time of national mourning for the 31 people who have died and the 35 reported missing.

She also said “Tropical Storm Erika demonstrates clearly the existential threat which storms exacerbated by warming and rising seas pose for small island states.”

Early Warning Systems and Disaster Preparedness

Margareta Wahlström pointed out the need for improved early warning systems for Dominica. “It is extraordinary that the island was expecting rain showers which would bring an end to a long period of drought but was not under a storm watch for an event which is estimated to have caused damages of $500 million and cost 50% of the island’s GDP and brought so many deaths.”

The disaster provides further evidence that small island states such as Dominica also need to strengthen disaster risk management and improve resiliency measures.

Ms Wahlström said:

“There are a number of lessons to be learned from this disaster. One major concern is the level of rainfall which accompanies such a storm system and how to prepare people and infrastructure for that eventuality. Over 30 centimetres of rain fell during a 12 hour period triggering floods and some 200 landslides with devastating consequences for the island’s future development including the loss to flooding of Melville Hall Airport which had only recently been renovated”.

“The Sendai Framework for Disaster Risk Reduction adopted as a global plan for reducing disaster losses has particular relevance for small island states where priorities for action must focus on strengthening disaster risk management, investing in resilient infrastructure, building back better and ensuring that adequate early warning systems are in place for events like this.”

One thought on “Dominica Floods Demonstrate Need for Improved Early Warning System

  1. Efficient early warning won’t reduce damages if flood hazard has not been modelled, mapped and most exposed and dangerous zones identified and evacuated of too exposed or vulnerable assets and resident people.
    What is missing in the Caribbean is more long term prevention than short term crisis tool such as early warning. But early warning is the shortest way to reduce victims.
