2 Atlantic Systems Lose Steam as El Niño-Driven Shear Dims Tropical Storm Dolly

3 articles · Updated · The Weather Channel · Aug 13

Two Atlantic disturbances tagged Invest 92L and 94L have seen their odds of becoming Tropical Storm Dolly fall, with forecasters saying both are gradually weakening.
Record-strong wind shear in the Caribbean and eastern Atlantic — intensified by a strengthening El Niño — plus pockets of dry air are disrupting organization and could tear the systems apart.
Invest 92L sits more than 500 miles east of the Lesser Antilles, while 94L trails farther east; if the lead system reaches the islands by Saturday, harsher shear may await.
Cristobal, the Atlantic season's third named storm, lasted only about 24 hours before degenerating into a remnant low, underscoring how hostile conditions remain.
The mainland U.S. faces little immediate threat, though the Lesser Antilles are urged to monitor forecasts as the basin moves toward the peak of hurricane season.
