Biscaya Bay
sting Jet



a sting Jet is a meteorological phenomenon
which has been postulated to cause some
of the most damaging Winds in extraTropical Cyclones
developing according to the Shapiro Keyser model
of oceanic Cyclones

vorrei farvi una domanda

ma ve la voglio proporre lo stesso ...
sapete dove si trova Newfoundland ( Terranova ) ?

Special Reportage ... Synopsis
in inglese

powerful WindStorm over the Bay of Biscay
North Spain and SW France

powerful sting Jet with damaging Winds 120 km/h -160 km/h
across the Bay of Biscay through the next 6 h -9 h

an impressive Airmass Satellite animation
of 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 Jet Stream
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 are out covering the System

latest Water Vapour Satellite analysis
of the rapidly developing ( RaCy )
and deepening secondary Low
over the Bay of Biscay

with currently near 985 mb central Pressure
and still deepening a potentially damaging Windtorm
is developing
we have highlighted the areas across
WSW France and NNW Spain
where the most severe Winds are expected
should locally exceed 150 km/h

rather small but significant secondary Low
will travel across Bay of Biscay tonight
and make Landfall in NW France towards the morning
its Windfield is pretty robust
and therefore a potentially damaging Windstorm
could result over WSW France
along the coastal areas and further inland
some models hinting Gusts in excess of 150 km/h
Stay Alert

P.S.: la data esatta è il 03.02.2017 ( San Biagio )
dai tanti Nomi dei Lows ( RaCy Cyclogenesis )
si è formato poi Leiv
