Barbuda Braces for Possible Tropical Storm Conditions from Erin

Barbuda is under a Tropical Storm Watch as Tropical Storm Erin moves closer to the northern Leeward Islands, with forecasters warning of heavy rain, strong winds, and dangerous seas this weekend.

Tropical storm conditions could reach Barbuda by early Saturday, bringing sustained winds near 70mph (110km/h) and higher gusts if the storm strengthens as expected. Erin is forecast to become a hurricane later today and could reach major hurricane status by the weekend.

The system is expected to produce 2–4 inches of rain across the northernmost Leeward Islands, with isolated totals up to 6 inches. This rainfall could trigger flash flooding, landslides, and mudslides in vulnerable areas.

Hazardous swells and rip currents generated by Erin are also expected to affect the northern Leewards, posing life-threatening conditions for swimmers and small craft.

Residents are urged to secure property, avoid coastal waters, and follow guidance from the Antigua and Barbuda Meteorological Service.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Tropical Storm Watch is in effect for…

  • Anguilla and Barbuda
  • St. Martin and St. Barthelemy
  • Saba and St. Eustatius
  • Sint Maarten

A Tropical Storm Watch means that tropical storm conditions are
possible within the watch area, generally within 48 hours.

Interests elsewhere in the northern Leeward Islands, Virgin Islands,
