Hurricane Danny Weakens, but Puerto Rico Braces It's now a category 1, expected to become tropical storm By Newser Editors and Wire Services Posted Aug 22, 2015 11:47 AM CDT 7 comments Comments This NOAA satellite image taken yesterday shows Danny when it was a category 3 hurricane. (Weather Underground via AP) (Newser) – The drought-stricken northern Caribbean is preparing for heavy rains and wind as a weakening Hurricane Danny approached Puerto Rico and the US Virgin Islands. The Category 1 hurricane was 600 miles east of the Leeward Islands this morning, with maximum sustained winds of 90 mph. It was traveling west-northwest at 12 mph. The US National Hurricane Center in Miami said it expected Danny would become a tropical storm between tomorrow and Monday. Track it via the NOAA here. A tropical storm watch is in effect for Antigua, Barbuda, St. Kitts, Nevis, Montserrat, Anguilla, St. Maarten, Saba, and St. Eustatius. Danny is expected to pass over Antigua and St. Kitts early Monday and hit the Virgin Islands and Puerto Rico early Tuesday. Surfline notes that any effects on the East Coast won't be felt until Tuesday or Wednesday, but the site says surfers hoping for great waves should "temper expectations."
