MIAMI, USA — Bermuda was under a tropical storm warning on Sunday as Tropical Storm Gert moved towards the island, strengthening slowly.
According to the National Hurricane Center in Miami, at 5:00 pm EDT, the center of Gert was located about 255 miles south-southeast of Bermuda moving toward the north-northwest near 8 mph. A gradual turn toward the north was expected later Sunday night or Monday morning
On the forecast track, the centre of Gert is expected to pass near or just east of Bermuda by Monday afternoon. Reports from an Air Force Reserve reconnaissance aircraft indicate that the maximum sustained winds have increased to near 45 mph, with higher gusts.
Additional strengthening is forecast during the next 48 hours. Tropical-storm-force winds extend outward up to 60 miles, mainly to the east of the centre. The estimated minimum central pressure is 1008 mb (29.77 inches).
Tropical storm conditions are expected on Bermuda late Sunday night or early Monday. Gert is expected to produce total rain accumulations of 1 to 3 inches on Bermuda. Large swells generated by Gert will begin to affect Bermuda later Sunday night and on Monday. These swells are likely to cause life-threatening surf and rip current conditions.
A tropical storm warning is in effect for Bermuda, which means that tropical storm conditions are expected within the warning area within the next 24 hours.
Meanwhile, a trough of low pressure located about 425 miles north-northeast of the northern Leeward Islands continues to produce limited shower and thunderstorm activity.
Satellite data and ship observations suggest that the system still may not have a closed surface circulation and environmental conditions are expected to remain only marginally conducive for development over the next couple of days due to proximity to Tropical Storm Gert.
This system has a medium chance — 30 percent — of becoming a tropical cyclone during the next 48 hours as it moves toward the west-northwestward at 15 to 20 mph.
Elsewhere, tropical cyclone formation is not expected during the next 48 hours.
