🟢 TROPICAL STORM ARTHUR FORMS

June 17, 2026

Tropical Storm Arthur has formed over the northwestern Gulf of Mexico, becoming the first named storm of the 2026 Atlantic Hurricane Season.

LOCATION: 28.8°N 95.5°W
MOVEMENT: NE at 9 mph
MAXIMUM SUSTAINED WINDS: 45 mph
MINIMUM CENTRAL PRESSURE: 999 mb

Tropical Storm Arthur developed after Potential Tropical Cyclone One became sufficiently organized over the warm waters of the Gulf of Mexico.

Satellite imagery, radar data, and surface observations indicate that Arthur has developed a well-defined circulation center and sustained tropical-storm-force winds.

Additional strengthening remains possible before Arthur makes landfall along the northern Gulf Coast. However, the system is expected to be relatively short-lived due to its proximity to land and increasing interaction with an approaching mid-latitude weather system.

⚠️ PRIMARY HAZARD: FLOODING

🌴 IMPACT TO THE CARIBBEAN - NONE

Tropical Storm Arthur remains well north of the Caribbean Sea and poses no threat to the Caribbean region at this time.

🔴 POTENTIAL TROPICAL CYCLONE ONE UPDATE

June 17, 2026

Potential Tropical Cyclone One is likely to become the first named storm of the 2026 Atlantic Hurricane Season.

LOCATION: 27.3°N 97.6°W
MOVEMENT: NE at 6 mph
MAXIMUM SUSTAINED WINDS: 30 mph
MINIMUM CENTRAL PRESSURE: 1005 mb

Satellite, radar, and surface observations indicate that the low-level circulation has become better defined, while atmospheric pressure continues to fall. However, the system still lacks a fully defined center and persistent organized thunderstorms needed to be classified as a tropical depression.

Environmental conditions, including warm Gulf waters and favorable upper-level winds, are expected to support additional strengthening. Most forecast models indicate that the system will become a tropical storm on Wednesday, potentially becoming the first named storm of the 2026 Atlantic Hurricane Season.

🌴 IMPACT TO THE CARIBBEAN- NONE

Potential Tropical Cyclone One remains well north of the Caribbean Sea and poses no threat to the Caribbean region at this time.
