Tropical Storms Peter and Rose have formed in the Atlantic within the last 24 hours. FOX 13 meteorologist Tyler Eliasen is keeping an eye on them but says neither storm poses a threat to the United States. Tropical Storm Peter may head toward Bermuda while Tropical Storm Rose heads out to sea. Eliasen is also keeping an eye on another system that has formed off the coast of Africa, which does is not an immediate threat, below:

The KHOU 11 Weather Team is monitoring the tropics, which is pretty active. We have Tropical Storm Peter, Tropical Storm Rose and Invest 98L as of September 20, in the video published on Sep. 20, 2021, “Tropics update: Tracking Tropical Storms Peter, Rose and Invest 98L“, below:
I’m more concerned about and am watching invest 98L for significant tropical storm development over the next 2 to 5 days as it’s located about 300 miles SW of the Cabo Verde islands off of Africa. Literally most of the global models continue to show the 98L will likely become our next named cyclone of the Atlantic hurricane season which will likely be Sam on our list of named storms. The latest HWRF and HMON models favor a Major hurricane with only the global ECMWF models also showing a major hurricane over the northern Leeward islands. The GFS for now is a northerly outlier and has a weaker solution at this time. But the question is how strong will invest 98L be as it reaches the northern leeward islands in about 7 to 10 days, in the video published on Sep. 21, 2021, “Hurricane Forecast Discussion, Very Concerning Invest 98L, Hurricane Sam Possible“, below:

At 06:00 UTC on September 11, the National Hurricane Center began monitoring a tropical wave expected to move off the west coast of Africa.[207] The wave moved westward across the central Atlantic for several days. By 03:00 UTC on September 19, it had more organized, with a well-defined center and deep convection, sufficient enough to be classified as a tropical depression.[208] Six hours later, it was upgraded to tropical storm status, and assigned the name Peter.[209] As the storm approached the northern Leeward Islands on September 20, it was being buffeted by a steady 25–30 knot southwesterly wind shear from a nearby upper low. As a result, Peter’s low-level center was displaced roughly 100 mi (160 km) west of its showers and thunderstorms, and the system was unable to undergo any major strengthening.[210]
Current storm information
As of 5:00 p.m. AST (21:00 UTC) September 20, Tropical Storm Peter is located within 30 nautical miles of 20.0°N 61.8°W, about 150 mi (240 km) northeast of the northern Leeward Islands. Maximum sustained winds are 45 knots (50 mph; 85 km/h), with gusts up to 55 knots (65 mph; 100 km/h). The minimum barometric pressure is 1007 mbar (29.74 inHg), and the system is moving west-northwest at 12 knots (14 mph; 22 km/h). Tropical-storm-force winds extend outward up to 125 miles (205 km) from the center.

At 00:00 UTC on September 15, the National Hurricane Center began monitoring a tropical wave approaching the Atlantic coast of Africa.[211]After moving into the far eastern tropical Atlantic, it formed a low pressure center, but remained disorganized. By 03:00 UTC on September 19, the disturbance had acquired a well-defined circulation and enough organized deep convection for it to be designated a tropical depression.[212] Later that day, satellite images showed that the deep convection had increased within the cyclone and that its overall structure had continued to improve. As a result, the cyclone was upgraded to a tropical storm and given the name Rose.[213]
Current storm information
As of 5:00 p.m. AST (21:00 UTC) September 20, Tropical Storm Rose is located within 30 nautical miles of 18.4°N 34.4°W, about 705 mi (1,135 km) west-northwest of the southernmost Cabo Verde Islands. Maximum sustained winds are 35 knots (40 mph; 65 km/h), with gusts up to 45 knots (50 mph; 85 km/h). The minimum barometric pressure is 1007 mbar (29.74 inHg), and the system is moving northwest at 15 knots (17 mph; 28 km/h). Tropical-storm-force winds extend outwards up to 35 miles (55 km) from the center.
