Scattered showers and lightning storms in Lake County will
continue moving east into the Orlando Metro, Volusia County and
eventually the far northern Space Coast. Further south, heavy
showers and lightning storms have also developed just west of
Interstate 95 along the Treasure Coast. These storms will remain
across mostly rural areas, though some rain is ongoing from Ft.
Pierce to Port St. Lucie to Palm City. These slow moving storms
will move into Okeechobee County later this afternoon.

Occasional lightning strikes and heavy downpours are the main threat
with storms today.

Expect lightning storms to continue to develop into the late
afternoon and evening as the east and west coast sea breezes collide
across the east-central Florida peninsula.
