eastern portions of the Mid-Atlantic states today.

small streams and creeks to overflow their banks across the
aforementioned regions. Minor to moderate river flooding is
occurring or forecast in Louisiana, Arkansas, and
northern Mississippi.

WIND: Winds with Laura are expected to increase near and
offshore the Mid-Atlantic coast as the low pressure system moves
