I just tested and confirmed the address I posted works on Pre2, Touchpad, and android Nexus 7 kk4.4 using chrome or dolphin browser. Radar and everything. Instant load, no ads.
With Firefox it fails. it redirects to the mobile site, and if you request desktop site, it changes "WebKit" to "xhtmlmp" in the address. The map does not display on the front page but does display on the maps/local page.
Oh you mean the rain on the map. Sorry.
I see purple clouds on infrared radar map over Texas but no rain over the whole country. But it's not raining anywhere right now.
Have to watch for this on a rainy day, but I've never had a problem with it.
