It can be flown whenever you want it to be.
But to answer the question SHOULD it be flown in the rain, no. It should be flown when the weather permits from sunrise to sunset, unless it's an all weather flag.
The American should be displayed 365 days a year from sunrise to sunset, with the exception of days it is raining. If it is raining at sunrise, you do not raise the flag. If it is not raining at sunrise, raise the flag; and if it starts to rain during the day, no matter the flag still stays up and you take it down at normal sunset.
Because if you put the flag in bad weather then that's disrespect.
There is not a set height that the American Flag needs to be flown at, but it does need to be flown at the top of the flagpole. If other flags, such as State or POW/MIA, are flown around the American flag then the American flag needs to be flown above the other flags.
You can but it's not good for the flag. The unofficial flag etiquette says that flags should not be flown in the rain.
NO. as approved by congress "NO STATE FLAG" shall be flown above the American Flag.
Any flag flown upside down is a signal of distress.
in rain weather. because you dont wanna disrespect the flag.
The American Flag should always be flown higher than the state flag and should be flown a half-mast when in peril or in rememberance.
Port
The United States flag can be flown in all kinds of weather. But, this is only possible when the flag is made of a weather-proof material.
The flag can not be flow in rain, thunder storms, tornados, huricanes, etc.
The American flag should be flown above a light as a sign of respect
From Dawn to Dusk
This will all depend on which flag is flying alongside or below the American flag. If being flown with flags of other nations, they should all be raised to the same height and are never to be flown on the same pole. If being flown with a state, city or organizational flag, the US flag will fly above the other flag in a larger size. On most standard sized flagpoles, the American flag will be a 3'x5' flag and the other flag will be a 2'x3' flag. If the US flag is flying along a different flag on separate flagpoles, the flags can be of equal height but the US flag will then need to fly on the extreme left of the other flags. This left side is known to be a prominent flag. When flown with flagpoles displaying non-national flags, the American flag will be raised first and lowered last. There is a link below.
