The tropical wave moving across the Atlantic currently has a 60 percent chance of become a tropical depression later this week.

The remnants of Odette could acquire some subtropical characteristics later this week as it moves over warmer waters. There’s a 30 percent chance for development over the next five days.

The next names on the list for the 2021 Atlantic hurricane season are Sam and Teresa.

Here’s the latest update from the NHC as of  5 a.m. Sept. 20:  

What’s out there and where are they?

Tropical Storm Peter: Peter is located about 245 miles east-northeast of the northern Leeward Islands, or 1,482 miles east of West Palm Beach.

Tropical Storm Rose: Rose is located 550 miles west of the Cabo Verde Islands, or 3,235 miles east of West Palm Beach.

Disturbance 1: A tropical wave located over the far eastern tropical Atlantic several hundred miles southeast of the Cabo Verde Islands is producing an area of disorganized showers and thunderstorms.

Disturbance 2: A storm-force, non-tropical low-pressure system, the remnants of Odette, is located a couple of hundred miles southeast of Newfoundland.

How likely are they to strengthen? 

Tropical Storm Peter: Maximum sustained winds are near 50 mph, with higher gusts. Slow weakening is forecast during the next several days. Tropical-storm-force winds extend outward up to 125 miles, primarily to the northeast of the center.

Tropical Storm Rose: Maximum sustained winds are near 40 mph, with higher gusts. Slight strengthening will be possible today. By Tuesday, however, upper-level winds are expected to become less conducive, and Rose is forecast to begin a slow weakening trend.

Who is likely to be impacted? 

Tropical Storm Peter: Rainfall around the southern periphery of Tropical Storm Peter could produce rainfall totals of 1 to 3 inches, with locally higher amounts possible, across portions of the Northern Leeward Islands, including the Virgin Islands, as well as Puerto Rico through Tuesday.

Swells generated by Peter are expected to affect the northern Leeward Islands early this week, and then reach the Bahamas by midweek. These swells could cause life-threatening surf and rip current conditions. 

Tropical Storm Rose: No impact to the U.S. is forecast at this time.

Disturbance 1:  No impact to the U.S. is expected at this time.

Disturbance 2 (Odette): Overall, Odette will bring some impacts to eastern Newfoundland putting a damper on cleanup efforts from Hurricane Larry, according to AccuWeather. Heavy downpours could bring areas of flash flooding. Gusty winds could become locally damaging, with power outages and coastal flooding also possible. 

Forecasters urge all residents to continue monitoring the tropics and to always be prepared during what’s expected to be an active hurricane season.
