MIAMI, Aug. 19 (UPI) — Tropical Storm Danny grew in strength overnight and the disturbance is expected to continue building as it moves closer to the Caribbean.
The 5-day forecast track has shifted slightly to the north, which would point the storm to the north end of the Lesser Antilles by Monday, according to the National Hurricane Center based in Miami. Puerto Rico could see some effects by Tuesday if the current track holds. No watches or warnings are in effect.
The storm is forecast to become a hurricane Thursday and reach Category 2 strength with 100-plus mph winds on Friday night and Saturday before weakening slightly on Sunday. Maximum sustained winds are currently at 50 mph.
NHC reports the storm’s cloud pattern did not change much overnight, with intermittent convection at the storm’s center. Good convection at the center helps the development of an eye wall, a sign of a strong, well organized hurricane.
