Hurricane Erin is marching north and is set to bring life-threatening rip currents, destructive waves, coastal flooding and possibly beach erosion to much of the East Coast. The conditions will last through Thursday before improving later on Friday and into Saturday.

The National Hurricane Center is tracking three systems in the Atlantic, according to the 8 a.m. Wednesday, Aug. 20, advisory.

The hurricane is now generating dangerous rip currents from Florida to New England, but it is not expected to make landfall in the US.
