I have had an alert today that a "Full Smith Period" has been recorded
in my postal area, BS31. That suggests that blight may occur as a
result.
Quote from their site defining a Full Smith Period:
At least two consecutive days where min temperature is 10ºC or above
and on each day at least 11 hours when the relative humidity is
greater than 90%.

Oh well, it was to be expected after all this wet weather.
