A high pressure ridge to the northeast and a steep pressure gradient is bringing brisk winds gusting to 30-mph along the Texas coast, along with higher than normal tides and dangerous rip currents. Already, a Small Craft Advisory is effect for off-shore waters through tomorrow morning.
Meanwhile, a short-wave trough moving east from the vicinity of Baja California and a coastal trough expected to form off the South Texas coast, should result in increasing rain chances, breezy conditions and elevated tides along the immediate coast through much of the weekend. Minor coastal flooding will be possible during high tides on both Saturday and Sunday.
While the heaviest rain will probably be off to the south of Galveston, precipitation amounts in excess of one inch will be possible right along the coast and to the south of Galveston County.
