Potential Tropical Cyclone SIX


Potential Tropical Cyclone Six Discussion Number   1
NWS National Hurricane Center Miami FL       AL062018
1100 AM AST Thu Aug 30 2018

The area of low pressure that moved off the coast of Africa has
continued to become better organized, and is producing a large
area of disturbed weather with gusty winds, but currently lacks a
well-defined center.  Environmental conditions are favorable for
additional development, and a tropical depression or a tropical
storm could form an any time today or Friday.  Given the high
chances that this system could bring tropical storm conditions to a
portion of the southern Cabo Verde Islands, advisories have been
initiated on Potential Tropical Cyclone Six.  Most of the intensity
guidance calls for strengthening and so does the NHC forecast.

The system is embedded within the easterly trades and this flow
pattern will steer the disturbance toward the west or west-
northwest during the next few days.  By the end of the forecast
period, a turn toward the northwest should begin as the system
reaches a weakness in the subtropical high.  This is consistent with
the output of the global models.
