Isaac Weakens Again!
Published 14th September 2018, 10:37pm
At 10 pm the centre of Tropical Storm Isaac was located near latitude 15.4 North, longitude 69.5 West. Isaac is moving toward the west near 15 mph (24 km/h) and this general motion with a slight decrease in forward speed is expected over the next couple of days. A turn toward the west-northwest or northwest is possible by the end of the weekend, if Isaac has not degenerated into a trough of low pressure by then.
Maximum sustained winds are near 40 mph (65 km/h) with higher gusts. The maximum winds are not expected to change very much during the next several days. Tropical-storm-force winds extend outward up to 45 miles (75 km) from the centre. The estimated minimum central pressure is 1002 mb (29.59 inches).
A ridge over the southwestern Atlantic should steer the cyclone westward over the weekend then west-northwestward early next week as Isaac reaches a weaker portion of the ridge. The system is forecast to be weaker, whether it a tropical wave / depression it is expected to bring cloudy rainy condition over the Cayman area, from Sunday night over Cayman Brac and Little Cayman and from early Monday morning over Grand Cayman as “ Isaac “ moves west, south of Grand Cayman. With the passage of the system we are expecting moderate southeasterly winds and moderate seas, showers may become locally heavy at times leading to possible flooding of low lying areas.
