The head of French civil security, Jacques Witkowski, told reporters in Paris on Tuesday that it was too soon to say whether the French archipelago of Guadeloupe was so lucky. Communications there have been difficult. He says two people suffered minor injuries.
The prefect, or highest French official, of Guadaloupe, Eric Maire, said in a video via Twitter that some roads and homes were flooded and heavy rain is expected to continue. He told island residents to "remain inside" amid the flood threat and warnings by forecasters of possible landslides.

That means parts of the island are expected to experience the full force of the storm's winds that have now reached 160 mph. Conditions are expected to deteriorate Tuesday night with the approach of the "extremely, extremely dangerous hurricane."
The Virgin Islands are already reeling from Hurricane Irma, which passed over the islands of St. Thomas and St. John.
