Shimla recorded 44.5cms of snow in 24 hrs ended on January 22nd.

Is it mm or cms ? If it is cms then 445 mm in 24 hrs is a deluge flooding! This is like 1 year of rain for parched TN / AP.

Love your weather tracking. Would love to discuss some things... how do I get in touch?

Depth of snow measurement is given and not the melted snow i guess. Snow is measured in cms so figures given are correct to my knowledge.

Snow is measured as solid precipitation in a snow guage. When converted to equivalent liquid precipitation, when the temperature is upto -6c, one inch of liquid precipitation would fall as 10 inches of snow -- assuming the storm is all snow. But, the amount of moisture in each snowflake differs depending on the temperature changing the snow to rain ratio.
Heavy, wet snow has a very high water content and 4 or 5 inches of heavy, wet snow can contain about one inch of water, while it may take 20 inches of dry, powdery snow to equal one inch of water. The 10=1 equation also assumes a 'perfect' snowmelt without evaporation or other losses.
So, for powdery snow the ratio may change, but as a rule we can take 1:10 ratio for snow upto -6c. Below -6c the ration chages and increases slightly.
so, 44 cms odf snow = 44 mms of equivalent rain.

In other words, the snow ratio is simply how much liquid would result if you melted the snow. The average snow ratio is 10 to 1 (10 inches of snow for 1 inch of liquid water), which is usually seen with temperatures near and upto -5/6c.
