🌬️ Intensity and Wind Field
- Maximum sustained winds: 45 mph (75 km/h)
- Wind gusts: Higher gusts possible
- Tropical-storm-force winds: Extend outward up to 140 miles (220 km) from the center
- Central pressure: 1002 mb (29.59 inches)
Although the storm may strengthen slightly in the short term, Dexter is expected to become post-tropical by Wednesday as it moves over cooler waters.
🌀 Development History
Dexter originated from a non-tropical low pressure system (formerly labeled AL95) that developed off the U.S. East Coast. Despite being attached to a frontal boundary early on, environmental conditions allowed it to gain tropical characteristics rapidly.
Over the last 48 hours, satellite data confirmed gale-force winds, prompting its upgrade to a tropical storm. This system had a 70% chance of tropical cyclone formation, as predicted in previous NHC outlooks.

🗺️ Impacts and Forecast Outlook
- No land impacts are expected.
- No watches or warnings are currently in effect.
- The storm is forecast to stay north of Bermuda and pose no threat to the U.S. East Coast.
While Dexter will likely remain over water, mariners in the region should continue to monitor NOAA’s High Seas Forecasts for potential rough conditions.
