Tracking three disturbances in the tropics

As of Wednesday morning, the National Hurricane Center is monitoring not one, not two, but three areas of disturbed weather in the Atlantic.

Two of the disturbances are currently named Invest 97-L and Invest 98-L. While there is plenty of uncertainty with each disturbance, both are likely to develop into a tropical depression or tropical storm.

The third area is a possible system with a 20-percent chance of development over the next five days and is located over Guinea, Africa.

The next names to be used from the 2020 Atlantic hurricane list are Laura and Marco.

It’s too early to tell if Florida could see any impacts from the storms.

Tropical Weather Outlook

NWS National Hurricane Center Miami FL 800 AM EDT Wed Aug 19 2020
For the North Atlantic…Caribbean Sea and the Gulf of Mexico:

  1. A tropical wave located over the eastern Caribbean Sea is producing
    disorganized showers and thunderstorms, along with gusty winds in
    these thunderstorms. Some gradual development of this system is
    possible over next day or so while it moves westward at about 15 to
    20 mph across the central Caribbean Sea. After that time, the wave
    is forecast to move more slowly west-northwestward, and a tropical
    depression is likely to form late this week or this weekend when the
    system reaches the northwestern Caribbean Sea.
  • Formation chance through 48 hours…medium…40 percent.
  • Formation chance through 5 days…high…80 percent.
  1. An elongated area of low pressure, located a little over 1000 miles
    east of the Windward Islands continues to produce a concentrated
    area of showers and thunderstorms mainly on the west side of the
    disturbance. Environmental conditions are conducive for further
    development, and a tropical depression is expected to form during
    the next day or two while the system moves generally
    west-northwestward at 15 to 20 mph across the central and western
    portions of the tropical Atlantic.
  • Formation chance through 48 hours…high…90 percent.
  • Formation chance through 5 days…high…90 percent.
  1. A large area of showers and thunderstorms, located over Guinea and
    Sierra-Leone, Africa, is associated with a vigorous tropical wave.
    Environmental conditions are expected to be marginally conducive for
    some development of this system while the wave enters the extreme
    eastern Atlantic on Friday. By early next week, however, conditions
    are forecast to become less favorable for tropical cyclone formation
    while it moves west-northwestward at 15 to 20 mph toward the central
    tropical Atlantic.
  • Formation chance through 48 hours…low…near 0 percent.
  • Formation chance through 5 days…low…20 percent.
