Expert opinion

Low 963 hPa centered at 160 nautical miles in the South-South-West of Fastnet Rock (South-West Ireland) moving at 17 knots to the North-East and dropping to 957 hPa to be centered on the Celtic Sea.

For Jullouville :
No gale warning.

We are 90% sure of the situation, because the high pressure system could move in more quickly than forecast.
