800 AM PDT MON AUG 11 2025
THE LAST BIT OF CONVECTION ASSOCIATED WITH IVO DISSIPATED ABOUT 15
HOURS AGO, AND IT HAS THEREFORE DEGENERATED INTO A REMNANT LOW.
MAXIMUM WINDS ARE ESTIMATED TO BE 25 KT, AND FURTHER WEAKENING IS
FORECAST AS THE SYSTEM MOVES OVER COLDER WATERS. IVO IS EXPECTED
TO OPEN UP INTO A TROUGH--AND THUS DISSIPATE--IN ABOUT 36 HOURS, AS
DEPICTED IN GLOBAL MODEL FIELDS. UNTIL THAT TIME, A LOW-LEVEL
RIDGE TO THE NORTH IS EXPECTED TO STEER THE REMNANT LOW WESTWARD AT
ABOUT 10 KT, AND NO MAJOR CHANGES WERE MADE TO THE OFFICIAL TRACK
FORECAST.
