TS Larry forms over the eastern tropical Atlantic, expected to strengthen

The twelfth named storm of the 2021 Atlantic hurricane season, Tropical Storm Larry, has formed over the eastern tropical Atlantic south of the Cabo Verde Islands. Larry is likely to intensify into a large and powerful hurricane over the next several days over the open Atlantic Ocean, and currently is not expected to threaten land.

As of 2:00 p.m. CVT (11:00 a.m. EDT), Tropical Storm Larry was centered near 12.3°N 27.6°W, and was moving westward at about 22 mph. Maximum sustained winds were 45 knots (50 mph), with an estimated minimum pressure of 1001 mb. During the next 48 hours or so, Larry is expected to be over sea surface temperatures warmer than 27°C (80.2°F), while wind shear is expected to be less than 10 knots and 700-500 mb relative humidity is expected to be above 60%. This environment is favorable for intensification, and Larry should become a hurricane tomorrow and potentially a major hurricane Friday night or Saturday. After that time, the shear is expected to increase and the mid-level relative humidity is expected to dry out a bit, which may limit intensification. Regardless, Larry is likely to become a large and powerful hurricane and be around for at least another week. At the moment, Larry appears very unlikely to pose a threat to the Caribbean or continental United States, though Bermuda may have to keep a close eye on Larry for potential impacts down the road.
