If this storm, or any other for that matter, have wind speeds within the realms of tropical storms or even hurricanes, do they receive a hurricane name or do they have to form further south in the tropics (hence the term tropical storm)?  Category details taken from Wikipedia below.  Abigail would appear to fall within the tropical storm classification for sustained wind speeds.  Is this storm not classified as a tropical storm because it formed too far north?

 

Hurricane Category Wind Speeds

 

Five ≥70 m/s, ≥137 knots
≥157 mph, ≥252 km/h

 

Four 58–70 m/s, 113–136 knots

Three 50–58 m/s, 96–112 knots

Two 43–49 m/s, 83–95 knots
96–110 mph, 154–177 km/h

 

One 33–42 m/s, 64–82 knots
74–95 mph, 119–153 km/h

 

Tropical storm 18–32 m/s, 34–63 knots
39–73 mph, 63–118 km/h

 

Tropical depression ≤17 m/s, ≤33 knots

Tropical storms/huricanes are formed over the warmer waters of the tropics and will be named (for example) by the National Hurricane Centre, if a hurricane moves poleward over cooler waters it loses it's tropical characteristics with the main energy source becoming baroclinic. A hurricane or tropical storm can still retain the wind strengths even after becoming extratropical.

 

Once this happens it will still keep it's name but will be referred to as ''Ex-hurricane......'' Or ''Ex-tropical storm......'' , Abigail has formed in the mid-north Atlantic so was never classed as a tropical storm. Also if an ex hurricane or tropical storm was to affect the UK it would still be called by it's original name and will not be renamed by the Met Office under the new storm naming scheme.

anyone know if this site has any accuracy? thanks

Never seen it before, and some of the current wind speeds look too high when compared to XC Weather data... For example St Bees Head Cumbria, that site is showing 54mph wind and XC shows 28mph....

Already been mentioned over in the convective thread, Torro have issued a tornado watch for most of the UK & Ireland away from southern counties, where the risk is lower.

 

http://www.torro.org.uk/forecast.php

 

 

 

A deep Atlantic low pressure system will push a well-marked cold front eastwards across the British Isles through today and tonight. Hi-res models simulate line convection (at times) as the front moves eastwards, but there are other morphologies too, including core/gap (more cellular) type elements too. In addition, there are indications of development within the warm conveyor belt too, and this is already occurring over southern Ireland. 

This latter activity could develop into deeper convection, and would be subject to marked wind shear, perhaps with supercells possible, anywhere from S Eire NNE through parts of the Irish Sea into NW England/S Scotland.

Abigail's central pressure has fallen slightly since the last update, currently 976mb.

Recent top wind gusts in the 60-70mph range for the north & west coasts of Ireland and Capel Curig 71mph, blowing a gale through the Irish Sea now ahead of the cold front which has become more fragmented, pouring down over Western Scotland.

Every school in the Western Isles and Shetland will be closed to pupils on Friday because of the expected arrival of Storm Abigail. All ferries on the Clyde and Hebrides network have already been affected by bad weather with more than half of the services on the 25 routes cancelled.

All I want is a big old storm right through the central belt, is that too much to ask?

Apart from Cairngorm Summit, Capel Curig has recorded the highest gust so far today, 75mph. http://www.xcweather.co.uk/

You'll be waiting a while longer I think, certainly not tonight or tomorrow.

Squally shower just went through. Gusts went from around 50mph to maybe 65mph in a matter of seconds!

Heavy rain here and squally winds, over the next few hours the real strength should start to be felt across the Western Isles.

Could there be a sting jet with Abigail or is it deepening too slowly for that?
