Tropical Cyclone 06L (Fiona) remains active over the Atlantic Ocean…located about 1095 miles west of the Cabo Verde Islands
Tropical Storm 06L (Fiona) remains active in the Atlantic…over the open ocean
Tropical Storm Fiona formed Wednesday evening in the central Atlantic Ocean…with no threat to land areas.
Tropical Storm 06L is moving toward the west-northwest at near 08 mph.
According to the National Hurricane Center (NHC), deep convection has decreased since the previous advisory, due to TS Fiona moving into the daytime convective minimum period, plus likely entrainment of dry mid-level air.
The forward speed has decreased sharply since the previous advisory, and Fiona is now moving at 300 degrees at 07 knots.
The intensity forecast is a little less straightforward than the track forecast due to mixed environmental signals. On one hand, wind shear conditions are expected to increase to more than 20 knots in 48-72 hours, while the storm is moving into a much drier air airmass.
This combination of negative parameters generally supports significant weakening. However, Fiona will also be moving over warmer sea waters, and into a region of much cooler upper-level temperatures, which will act to generate greater instability and likely more vigorous and persistent convection…despite the drier mid-level environment.
The long shot in the future is that what’s left of this storm, could end up somewhere near Bermuda…around the middle of next week.
