Of course, even in the more remote areas, we can usually pick up a cell signal every day or two to check weather forecasts.
Before loading anything extra to take up space on the bike and in the brain, I always remind myself, it is supposed to be adventure cycling, and the adventure is provided by the unknown. Just a thought.
Unknown can be fun, as long as it's not a tornado, or extremely high winds that could shred a tent either from the wind itself or tree branches flying into it, or extremely heavy rain for a long period of time. Even a good tent, short of it being made of Dyneema, will leak rain in if the fabric gets saturated, and you didn't spray it with waterproofing and reseal the seams just before you left on tour.
Leakage can result from a combination of factors like capillary action, surface tension, and to a lesser degree hydrostatic head. Hydrostatic head has to do with the numbers that a tent manufacturer will put on their rain fly to withstand water, the lower the number the less pressure the fabric can take before allowing water in. Dyneema has a very high number, but it also doesn't breathe which allows for condensation to form. Capillary action has a lot to do with Hydrostatic head, the smaller the fabric "pores" are the less water can penetrate. Surface tension is about gravity, as the water pools in a certain area on the tent. The driving reason for leakage is the surface tension, but it can also be the result of a tent with an insufficient hydrostatic head.
This is why it's important to not have anything touching the wall of the tent, which can be difficult to do in small bikepacking tents. It's also important to spray waterproofing stuff on the tent and reseal the seams every season, though some experts suggest doing it after every heavy rain, they seem to think that heavy rain can wash some of the waterproofing off the fabric, but it would be sort of a pain to take waterproofing spray and sealant with you on a long tour, and then once you spray the tent you have to wait 12 hours before you can put it away! Also, I found out from my tent manufacturer that you need to contact the maker of your tent and ask them which waterproofing spray they recommend to use on your tent, for some reason some brands of waterproofing may do little to waterproof your particular fabric, and could even ruin the fabric, same with the seam sealant.
I'm not an expert on this stuff so feel free to correct anything I've said, I'm learning along with most of you.
