The U.S. National Hurricane Center (NHC) is issuing advisories for Hurricane Sergio and Hurricane Leslie.

Hurricane Leslie

In its 11 a.m. update on Oct. 4, the NHC said Leslie is now a Category 1 hurricane and is circling around the central Atlantic Ocean. It is hundreds of miles from any landmass. The NHC said that it is about 445 miles east of Bermuda and is moving to the north.

The forecast model shows that Leslie will continue to move north before moving to the east. “A reduction in speed is forecast on Friday and Friday night, with Leslie turning toward the east or east-southeast over the weekend,” the agency said.

There are no coastal watches or warnings in effect, according to the weather agency.

Leslie will continue to generate large swells in the ocean water along the East Coast of the United States, Bermuda, and the Bahamas for the next several days.

“Swells are expected to increase near the coasts of New England and Atlantic Canada by the end of the week,” the agency said.

When Leslie moves to the north, the storm will run out of warm water and will gradually weaken, according to the NHC’s discussion.

“Sergio is moving toward the northwest near 9 mph (15 km/h) and this motion is expected to continue today. A turn toward the west-northwest and west at a slightly slower forward speed is expected Friday and Saturday,” according to the NHC at 11 a.m.

There will not likely be any fluctuation in Sergio’s strength over the coming days, according to the NHC. By Friday, the storm will gradually weaken.

Rosa

The remnants of Hurricane Rosa, which hit Mexico as a tropical storm before it weakened to a tropical depression and hit the southwestern United States, has triggered flooding concerns in Arizona.

AzCentral, citing tribal officials, reported that Rosa’s rains produced “unprecedented levels of flooding on the Tohono O’odham Nation, particularly in the vicinity of the Menagers Dam community.”

Residents of the Menagers Dam community near Sells, Arizona, were evacuated because of “uncertainty over the integrity of the dam,” officials said.

The National Weather Service office in Tuscon painted a more dire picture, issuing a warning on Oct. 2.

“Dam failure is imminent at Menagers Lake on the Tohono O'odham Nation. Evacuation per authorities is strongly advised for the village of Ali Chuk,” said the office on Twitter.

Sen. Jon Kyl (R-Ariz.) said on Oct 3: “I am closely monitoring developments impacting the community of Ali Chuk, Arizona, which was displaced by flooding on the Tohono O'odham Indian Reservation. Over 100 tribal members were evacuated when the Menagers Dam was overwhelmed by remnants of Hurricane Rosa,” AZCentral reported.
