A Tropical Storm Watch means that tropical storm conditions are possible somewhere within the watch area within 36 hours, in this case within 24 hours.

The centre of Tropical Storm Fiona has been wobbling slightly south and as a result a Tropical Storm Watch is being issued.

Movement: West at 15mph (24km/h)

Maximum sustained winds are near 50 mph (85 km/h) with higher gusts.

Tropical-storm-force winds extend outward up to 125 miles (200km) NE from the centre and about 100 miles (161km) SE. The system is expected to pass approximately 50 miles to the north of Dominica tonight.

  • Seas up to 12.0ft on the northern through eastern coastline today with swells occurring on the western coast tonight

EXPECTED IMPACTS:
