I can only speak from my experiences and what a wise ole man taught me.
Deer rely on their 3 major senses
Sight
Smell
Hearing
If you take away 1 sense they still move
If you take away 2 senses they move less
If you take away all 3 senses they tend to sit tight
Meaning if its raining hard and windy they cant smell or see or hear to well since the wind is doing funny stuff so everthing is moving cause its blowing around and the sound of the rain and wind makes it so they cant hear anything else and they cant smell in a pouring rain with winds swirlling around.
Now if its a light rain alone I'll hunt, but if its pouring I'll pass till its starting to ease up.
But I always see them moving right after the rain stops
But then again with the rut so close .... anything goes and none of this can apply and it all goes out the window.
Example had a fellow hunting a friends property
on a windy rainy day... he dropped a monster that scored 212 with his bow... hunting down in a steep ravine to get out of the wind close to rut time.
Hope you dont get a cold real bad and you feel better
