Powerful windstorm over the Bay of Biscay, N Spain and SW France – Feb 4th, 2017

*** Powerful sting jet with damaging winds 120-160 km/h across the Bay of Biscay through the next 6-9 hours ***

An impressive airmass satellite animation of thr rapidly developing secondary cyclone over the Bay of Biscay is revealing a potentially dangerous situation unfolding. Being placed in the left-exit of a strong jetstream, a quite significant deepening of the low is ongoing and should continue for a few more hours. Favorable kinematics and dynamics of the wind field could result in a powerful sting jet developing through the next hours and therefore, extremely severe and damaging winds are expected across coastal N-NW Spain towards WSW France until late morning hours as the deep low moves ashore. Expect gusts in excess of 150 km/h locally!

Stay alert for a possible widespread damage and stay safe if you’re out covering the system!

GFS model forecast for tonight, an extremely severe winds are expected!
