Tropical Storm Harvey: See new projected track, potential New Orleans, Baton rouge impacts, more | Weather/Traffic

Rain associated with Tropical Storm Harvey has started to smack southeastern Louisiana, with heavy rainfall expected Tuesday as the storm continues its slow churn in the Gulf of Mexico

As of 10 p.m. Monday, the National Hurricane Center said Harvey continued to move toward the east-southeast at about 3 mph with maximum sustained winds of 45 mph. Little change in strength is forecast during the next 48 hours.

The storm’s motion should continue with a slow turn toward the northeast Tuesday. The NHC said Harvey’s center is expected to be just offshore of the middle and upper coasts of Texas through Tuesday night before moving inland over the northwestern Gulf coast on Wednesday.

They also bring with them a threat of tornadoes, he said.
