You can't upload history. Not much point anyway as only past 30 days worth of data are kept.
No rainfall data is available. It's ingested but not available. Perhaps it will in the future.
Not sure about pressure on mobile. Maybe someone else can answer that.
Weather upload interval will update after 1 week.
Another webcam worth adding:

@ivo Thanks for your swift reply. I know how go to settings, click "show historical data", choose the date in the calendar and then close it, then mark a coordinate of interest to show wind data on it, after I click the "play" video button and watch the animation, as the red time line bar shows progress through the days ahead. MY QUESTION really is HOW can I turn this animation (including the point of interest marker, if possible) into a video link that I can post in my facebook so that my friends can click "Play" and reproduce and see the same animation I saw on my own Windyty screen, in a similar manner to those videos or movies that you show on your own Windyty facebook. I am trying to help with a search and rescue operation for a missing sailboat that was caught in a storm and probable remained dismasted and adrift. Such a viedo/movie may help estimate the subsequent drift pattern od the drifting sailboat.
