Invest 99 is getting its act together in the middle of the Atlantic Ocean. It is now sitting about 1000 miles east of the Southernmost Windward Islands. As of Wednesday morning, there are more showers and t-storms around its center of circulation.
NHC is giving it a 60% chance of becoming a depression or tropical storm over the next 48 hours . Upper air conditions are favorable for that to happen since there are no wind currents to stop it or cut it down.
Most models push this low west, impacting the Windward Islands in a few days. By then it could be "Ernesto".
Everyone in the Caribbean should monitor this system closely.
