Climate Prediction Center’s Hispaniola Hazards Outlook May 31 – June 6, 2018
The lack of rain over the past several weeks has resulted in abnormal dryness in northern Dominican Republic.
Since late April to present, below-average rain has fallen over Hispaniola, with the largest (> 100 mm) deficits over north- central Dominican Republic. Due to a poor rainfall distribution over the past thirty days, accumulated rain accounted for only less than 25 percent of the average over north-central and eastern Dominican Republic. Negative rainfall anomalies also emerged over portions of central Haiti, while positive rainfall anomalies persisted over parts of the southern Peninsula of the country. From May 22-28, suppressed rain again prevailed over much of the Island, except central Haiti and bordering western Dominican Republic, where light to locally moderate rain was registered, according to satellite rainfall estimates. The return of a favorable rainfall distribution is much needed to reduce moisture deficits, mitigate dryness, and alleviate the potential negative impacts of poor rain on cropping activities over many local areas. During the next week, little to light rain is forecast to continue throughout Hispaniola. However, moderate rain is possible over north- central Haiti and central Dominican Republic.
