Subtropical Storm Olga knocked out power and caused widespread flooding in Puerto Rico on Tuesday and threatened the Caribbean island of Hispaniola with torrential downpours and mudslides.
Olga was a relatively weak storm with top sustained winds of 45 mph and forecasters at the U.S. National Hurricane Center predicted strong winds in the upper atmosphere would start to tug it apart on Wednesday.
They said Olga's greatest threat was its torrential rains.
'These rains have already produced life-threatening flash floods and mudslides in Puerto Rico,' the forecasters said in an advisory.
Tropical storm warnings and watches were issued for parts of Haiti and the Dominican Republic, which share the island of Hispaniola, and for the Turks and Caicos islands and the southeastern Bahamas.

New passenger car registrations in the European Union in November fell 1.3 percent to 1.217 million vehicles from a year ago but were up 0.9 percent over the first 11 months, the ACEA European car association said on Friday.

ACEA said private demand in most of the countries of western Europe was damped by sharp rises in fuel prices, loss of purchasing power and regulatory changes.

The European Medicines Agency said on Friday that new warnings for doctors and patients were needed to increase awareness of cases of suicidal thoughts linked to Pfizer Inc's new smoking cessation pill.
Pfizer has been asked to submit changes to the marketing information for the product— sold as Champix in Europe and Chantix in the United States—before DeC.19.
The move follows similar action by the U.S. Food and Drug Administration, which issued a warning last month about Chantix, amid reports of suicidal thoughts and behaviour, and at least one death potentially linked to the medication.
Pfizer said there was no scientific evidence establishing a causal relationship between its medicine and these reported events, adding it was working closely with the European watchdog to review case histories.
