MIDWAY, Fla. (WTXL) -- Aside from Hurricane Florence, there are several other active spots in the tropical Atlantic basin:

  • Hurricane Helene in the eastern Atlantic is on a northerly track, remaining in the open ocean waters and forecast to weaken as it near the Azores by this weekend and possibly the British Isles beyond that time.
  • Tropical Storm Isaac continues its struggles again dry air and moderate upper-level wind shear.  Isaac is moving west at 21 mph and is 450 miles east of the Lesser Antilles island chain. Faster upper-level winds in the Caribbean will likely keep Isaac from significantly strengthening through late this week.  The system may still move into the western Caribbean waters into early next week, but its form at that time is somewhat unclear.
  • "Invest 95L" in the southwestern Gulf is moving west-northwest away from the northern Yucatan Peninsula. The disturbance has decent chances to develop into a tropical depression or storm before heading toward the Texas coastline, with very warm western Gulf waters in its path.  It is not expected to have a direct impact on the Big Bend's weather pattern.
  • An upper swirl in the northern latitudes of the Atlantic has developed into Subtropical Storm Joyce and will likely stay over open waters throughout its life span.
