Tropical Storm Isaias ninth named storm of 2020 hurricane season

30 Jul 2020 / South Florida, United States

Tropical Storm Isaias, which became the ninth named storm of a busy 2020 hurricane season late Wednesday (29 July) night, saw its forecast track make a small move to the east in today’s 5am advisory from the National Hurricane Center.

The center of that track keeps the core of the storm slightly off the shores of South Florida. All of South Florida, however, remains in the forecast path of a storm that had tropical-storm-force winds extending up to 415 miles from the center in the latest advisory.

The system is projected to remain a tropical storm for its foreseeable duration (maximum sustained surface winds ranging from 39-73 mph).

At 5am EDT Tropical Storm Isaias was some 100 miles WSW of Ponce Puerto Rico moving NW at 21 mph. maximum sustained winds are near 60 mph with higher gusts. little change in strength is anticipated before landfall in the Dominican Republic later today with re-strengthening on Friday and Saturday.

It is expected to continue aiming northwest with a dead-center pass over Hispaniola (the island that comprises the Dominican Republic and Haiti), contending with mountains as high as 10,000 feet.

Isaias is expected to continue on a northwest track until it reaches Florida, where a turn north is anticipated.

Tropical storm-force gusts could arrive Florida as early as Friday night, but Saturday is much more likely. The wind field is massive, with tropical-storm-force winds extending up to 415 miles north from the system’s center.
