Overview
- Tropical Storm Dolly formed in the central Atlantic on Thursday, Aug. 27, and is the fourth named storm of the 2026 Atlantic season.
- Forecasters say strong El Niño‑related wind shear should quickly weaken Dolly but its remnants may bring increased rainfall to Puerto Rico and the northeastern Caribbean over the weekend.
- The Mexican Servicio Meteorológico Nacional places Karina about 1,330 km south of Cabo San Lucas with sustained winds near 75 km/h, and the NHC warns its swell could cause dangerous surf and life‑threatening rip currents along parts of southwestern Mexico and Baja.
- Lowell is farther offshore, roughly 2,840 km west‑southwest of Cabo San Lucas with sustained winds near 65 km/h, and both Pacific storms are being tracked for possible strengthening though no broad Mexican landfall watches are in effect.
- SMN, CONAGUA and the NHC are issuing regular updates and advise mariners and coastal communities to monitor local forecasts; meteorologists note El Niño is increasing Atlantic wind shear even as Pacific development remains more favorable this season.
