Snow cover now disappeared and eveywhere looks green. Still some snow cover
around Hay Tor summit (looking out of top bedroom window). Patches of snow/hail
where it has blown.
Warm sunshine in between showers but wind is fierce and is almost certainly
storm force above 500m (so not a day for venturing high on Dartmoor unless you
have Arctic clothing and plenty of experience and good equipment).

Rainfall 4.8 mm since midnight (AWS) (but some missed due to horizontal snow)
Bar 1011 hPa steady
