Gale Warning
AMZ400-222215-
Synopsis for Altamaha Sound GA to Flagler Beach FL out to 60 nm-
915 AM EST Wed Jan 22 2020
.SYNOPSIS...
Low pressure strengthening just northeast of the Bahamas will
pivot eastward this afternoon as arctic high pressure moves
eastward and reaches the Mid-Atlantic coast by Thursday morning.
Strong northerly winds with frequent Gale Force gusts today will
gradually weaken overnight as a coastal trough develops over the
near shore waters, which will generate scattered showers through
Thursday. Winds will shift to northeasterly on Thursday as the
coastal trough moves onshore and high pressure gradually weakens
over coastal New England. Meanwhile, weak low pressure developing
over the lower Mississippi Valley on Thursday will shift north-
northeastward through the Tennessee and Ohio Valleys on Friday,
dragging a cold front across our waters on Friday afternoon and
evening. High pressure will then build into our region from the
west this weekend, with offshore winds expected in the wake of the
frontal passage. Seas will remain elevated over the offshore
waters through Saturday before gradually subsiding late in the
weekend.
