EUROPEAN WINDSTORM (EW) RHIANNON DISCUSSION NUMBER 1
KIEWII-COBRASTRIKE GACC DUNDEE UK
0900 UTC WED 18 JULY 2012

...RHIANNON HAS ENOUGH ORGANIZATION TO BE CLASSIFIED AS A EW. THE SYSTEM HAS
COMPLEX FRONTAL FEATURES WHICH HAS RAISED THE KCSGACC SATELLITE ESTIMATES TO
E3.0/45 KT. HOWEVER...DUE TO THE PROXIMITY OF LAND AND ALSO THE FACT THAT IT
HAS JUST FORMED...THE INITAL INTENSITY IS 30 KT...

...THE STORM WILL BE A FAST MOVER. AT THE MOMENT...RHIANNON IS OVER WESTERN
SCOTLAND AND SHOULD MOVE OVER THE NORTH SEA BY HOUR 12. GALE-FORCE WINDS
SHOULD BE ATTAINED BY THE SAME TIME. LANDFALL ON DENMARK COULD BE AS SOON AS
HOUR 24 AND THEN RHIANNON COULD BE OVER SWEDEN BY HOUR 36...
