The weather, however, is still as active during the night as it is during the day. Some significant weather situations such as rain, thunderstorms, and wind can and do occur during the night. In particular, the conditions associated with cold weather such as snow, frosts, and fogs are more likely to occur during the night. Night weather conditions therefore influence everyone in one way or another. Cold conditions require heating indoors.
Thunderstorms occurring the night can cause blackouts.
On the other hand, there are those people that work during the night in shifts. They are more directly influenced by the external night weather conditions. For instance, travelling during the night introduces reduced visibility. Flooded creeks or large puddles can be difficult to see. This section covers briefly many observations that can be made during the night using various techniques.
