how to spawn a no rain clip?

i havent used radiant in a long time, if i dl it will it tell me how to script a rain clip in a stock map? I was thinking something like -

rain:
level.rain_length = "50"
level.rain_width = "0.6"
level.rain_density = "12"
level.rain_min_dist = "2048"
end

shelter:
local.clip = spawn script_object
local.clip.origin = ( x y z )
local.clip setsize ( -500 -500 -10 ) ( 500 500 1000 )
local.clip //??? stop rain ???? func_rain ??? something to set it ??
end

or maybe something like -

shelter:
local.clip = spawn script_object "targetname" "shield"
local.clip.origin = ( x y z )
local.clip setsize ( -500 -500 -10 ) ( 500 500 1000 )
$shield immune rain
end

anybody??
