The remains of a stalled front will continue to bring scattered
showers and thunderstorms over the coastal locations and Gulf
waters today. Some of the stronger storms will be capable of
producing locally heavy rainfall and gusty winds. Winds outside of
storms will generally be light and variable, while becoming
erratic and gusty in and around any storms. Rain chances decrease
significantly by the middle of the week, while winds and seas are
expected to remain rather light and low.
