CURRENT TROPICAL CYCLONES:
Remnants of Tropical Cyclone 11L (Jose)…is located about 1170 miles northeast of Bermuda – Last Advisory
Post-Tropical Cyclone 10L (Idalia)…is located about 100 miles west of Bermuda
Tropical Cyclone Gert…is located about 655 miles east-southeast of Bermuda

Remnants of Tropical Cyclone 11L (Jose) – Last Advisory
JOSE ABSORBED INTO POST-TROPICAL CYCLONE FRANKLIN
According to the NHC Advisory number 15…
The remnants are moving toward the northeast near 23 mph (37 km/h). Maximum sustained winds are near 45 mph (75 km/h) with higher gusts. Tropical-storm-force winds extend outward up to 70 miles (110 km) from the center.
Post-Tropical Cyclone 10L (Idalia)
TROPICAL STORM FORCE WIND GUSTS REPORTED ON BERMUDA
According to the NHC Advisory number 26A…
The post-tropical cyclone is moving toward the east near 14 mph (22 km/h) and this general trajectory at a slower forward speed is expected through today. A turn toward the northeast is forecast on Sunday. On the forecast track, Idalia will remain near Bermuda today, and then begin to move away from the island on Sunday.
Maximum sustained winds are near 50 mph (85 km/h) with higher gusts. Little change in strength is forecast during the next few days. Idalia could transition to a tropical or subtropical storm later today.
Tropical-storm-force winds extend outward up to 220 miles (350 km) from the center. A wind gust to 40 mph (65 km/h) was recently reported at the LF Wade International Airport on Bermuda. An elevated observing site at the National Museum of Bermuda recently reported sustained winds of 46 mph (74 km/h) with a gust to 54 mph (87 km/h).
HAZARDS AFFECTING LAND
RAINFALL: Idalia is expected to produce rainfall amounts of 3 to 5 inches, or 75 to 125 millimeters, across Bermuda through Sunday night. The heavy rainfall will likely cause areas of flash and urban flooding on the island.
WIND: Tropical storm conditions are expected on Bermuda by Saturday.
SURF: Swells generated by Idalia will affect the southeastern U.S. coast and Bermuda during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions.
Tropical Cyclone Gert
GERT A LITTLE STRONGER WHILE REMAINING STATIONARY
According to the NHC Advisory number 17…
Gert is stationary. A northward motion is expected to begin on Saturday and continue into Sunday.
Maximum sustained winds are near 45 mph (75 km/h) with higher gusts.
Little change in strength is forecast before Gert becomes absorbed by Idalia by early Monday.
Tropical-storm-force winds extend outward up to 35 miles (55 km) from the center.
Tropical Cyclone 12L
TROPICAL DEPRESSION COULD BECOME A BRIEF TROPICAL STORM ON SATURDAY
According to the NHC Advisory number 3…
The depression is moving toward the north near 13 mph (20 km/h). A turn to northwest is expected shortly and this general motion with a decrease in forward speed is expected through Monday.
Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some strengthening is possible, and the depression could become a tropical storm on later today. Weakening is expected to begin by early Sunday, and the system could degenerate into a remnant low by late Sunday.
