Nothing similar to that; Houston got flooded by Allison awhile ago but we weren't affected. Our neighborhood is elevated several feet; essentially, if water even reaches my doorstep, the rest of Houston is already underwater.
At least the flood did not cut you off from the forums. Sometimes flood can take out the phone lines too. (Oh I forgot, you may be using wireless internet.)
Good to know you're still ok. The currents could have dragged you away.
