An unusually precise forecast from Weather Action:

"What will happen to that DEEP LOW 15th (currently similar to 12th on Forecast maps)?

WeatherAction Answer.
It will NOT be as severe as MO say. The Central pressure 960 mb at 00z 15th over Eire/Irish sea will be higher, and the centre will not have advanced so fast. The system will fill somewaht (sic) as it proceeds from now (13th 11z). The reason? We are now moving from an R5 into an an R3 period and Standard Met cannot well forecast out of an R5."

Normally the wording is so fuzzy as to enable claims of accuracy regardless of the actual outcome, so it will be interesting to see what the Central (sic) pressure is at midnight.
BTW - Anybody with a legal background able to tell me whether calling somebody a charlatan (as Byron Spicer does with Dame Slingo) is libellous?

Thanks
