At this time in the Atlantic basin we now have two invests designated by the NHC. Both of them pose a threat to develop and I will briefly cover both areas.
Invest 92L:
92L is currently heading WNW towards the Lesser Antilles. Convection is becoming more pronounced and concentrated tonight and the chance for a tropical depression to develop in the next 48 hours is 75%. A circulation is not very apparent at this time and to see a tropical depression form a closed surface circulation needs to become visible. Various satellite imagerys show convection consolidating and becoming better organized over the past few hours however a circulation remains unpresent. Most computer models hint at some slow development of this area of the next few days but none of the models show it posing a threat to the United States. All models take this disturbance out to sea and away from the U.S. East Coast.
Invest 93L:
93L is currently becoming slightly better organized but does not pose much threat to develop and if it does indeed develop it does not appear to be a threat to the United States. I will update on this system as needed.
