Having to fly low due to bad weather and or low visbility can be a sign of bad planning or judgement. Consider not going if there is any doubt as to the weather or visibility on the proposed route. If airborne and find conditions deteriorating, consider diverting to another aerodrome or carrying out a precuationary landing somewhere if things are beyond your ability. However, flying low at legal heights is okay if you are both competent, sensible and have an escape route should things turn to custard.
The margins for error are greatly reduced at low level and certainly, as Genghis says, navigation is very different due to the lack of visibility range. It is easy if you are unaccustomed to flying low to become disorientated. A common error is to assume you know where you are because you think you have travelled further than you really have (remember things appear to be faster at low level because drift and ground speed are more apparent). Keep navigating. But remember, as always, AVIATE NAVIGATE COMMUNICATE.
Anyway, a few thoughts on low flying based on my own experiences.
