Blight spreads when it is warm and humid for a 48 hour period, called a 'Smith Period'.
It has certainly been warm and humid recently but perhaps the humidity dropped below the required figure (80% I think). It definitely remained above 10 degrees C. for some time, even overnight!
I checked my registration with the website and confirmed I am still on the list to receive warnings for this area - but there is nothing to stop you registering if you wish to get the warnings direct. Just search 'Blightwatch' on the web.
