Impact Analysis by the Caribbean Institute for Meteorology and Hydrology (CIMH)

The Caribbean Institute for Meteorology and Hydrology (CIMH) provided CDEMA with an impact analysis based on the forecasted track of Hurricane Irma at 4:30pm, Sunday September 3, 2017.

RAINFALL: Satellite-based rainfall estimates show rainfall in excess of 350mm. Rainfall and reflectivity projections suggest intense rainfall can be expected with the passage of Irma

FLOOD/LANDSLIDE: Rainfall likely to lead to swollen river conditions, dangerous flash flooding and landslides but not expected to affect land within the next 48 hours. Interests should continue to monitor the track closely.

WIND: Winds likely to approach Hurricane force with stronger gusts in areas of thunderstorms later Tuesday into Wednesday. Hurricane force winds are very dangerous and will produce damages. Interests should continue to monitor the track closely.

WAVES: Waves heights likely to exceed 6.5 metres mainly in the Northern Leeward Islands. Storm surge and rough seas expected with damage likely along coastlines. Areas to the south could experience wave heights in the range of 3.5 to 4 meters. Near shore and marine operators should exercise caution.

In summary: Hurricane Irma is expected to be a major storm as it approaches the Leeward Islands on Tuesday into Wednesday. This will be accompanied by very strong winds, high storm surge and heavy rainfall.
