Just to remind some and make others aware
When there is snow around and it is raining, the chances of caves flooding is considerably higher.
Also note that although snow might not be evident on the ground near a cave entrance, the stream flowing through a cave might have it's source higher up a hill where there are still plenty of snow......
If it is raining, then the temperature is high enough to melt snow.
Even though a hill side might be largely clear of snow, snow drifts banked against walls contain a lot of frozen water which when it melts can cause a considerable release of water, which can then cause a dramatic knock on effect underground...
Also....
Direct observation may show that water levels to quite low, beware .... this might be the consequence of an overnight freeze...... which may be followed by a day time thaw......
