Civil Defense has maintained the red flag on beaches along the Puerto Plata coastline due to dangerous marine conditions, including strong currents, rip currents and abnormal waves.
Although conditions along the Atlantic coast have gradually improved, authorities said swimming remains prohibited on beaches under the alert as a preventive measure.
In a notice updated this Monday, the Civil Defense warned that rip currents can pull swimmers out to sea even when waves appear moderate.
The agency urged residents, tourists and visitors to respect the warning signs and avoid entering the water while the red flag remains in effect.
Civil Defense said it will continue monitoring coastal conditions and will notify the public of any changes. The swimming ban remains in place until further notice.
