At 5am EDT Wednesday, Tropical Storm Lisa was still drifting slowly and erratically east-northeastward, moving at less than 5mph, about 450 miles northwest of the Cape Verde Islands, which is over 3,140 miles from Florida.
Maximum sustained winds are still around 45mph, but environmental conditions could promote some slow strengthening. There is less than a 30% chance that Lisa will become a hurricane and the official forecast keeps Lisa at tropical storm strength through the next 5 days.
Lisa is expected to move slowly west-northwest at less than 5mph, keeping the storm well away from any landmasses through Monday.
A tropical wave over the eastern Caribbean Sea has not changed much in organization since yestereday evening, but has gained a center of low pressure.
There is now a 60% chance of this wave becoming a tropical depression today or tomorrow due to favorable environmental conditions for development in the Caribbean Sea.
Computer models are in good agreement as steering currents will bring the system west through the Caribbean through the next 3 days before turning northwest towards the Yucatan on Sunday or Monday. Long term computer models suggest a northward movement either into the Gulf of Mexico or across central Cuba in about 6-7 days, but it is too early to tell if this system will have an impact on Florida.
