 .Synopsis For High Island to the Matagorda Ship Channel Out 60 NM
 including Galveston and Matagorda Bays.
 
 Tropical Storm Isaias is expected to become a hurricane before
 moving ashore into the central Gulf Coast later this week. Though
 it should track well to our east, we may still experience
 increasing Gulf seas, swells, and winds later today through early
 Saturday. We continue to think Small Craft conditions are likely
 in the offshore Gulf. Winds and seas should decrease late
 Saturday into Sunday. Water levels will also run above normal,
 possibly nearing Coastal Flood Advisory thresholds by Friday.
