Saw your posts about the evacuation ordeal and your plans to stay in Pasadena. Most of Pasadena should be safer than Clear Lake (except of course the sliver on the lake and bay), and at a slightly higher elevation. Here are topo maps if you'd like to check, and earlier on this thread posted links to storm surge maps, just search my posting history. Zoom in and out using the sidebar. The lowest 2 levels have the actual height in feet above sea level.

Also at the actual start of this thread is a link to a detailed map of flood zones of all kinds in the Houston area, including Pasadena. Remember, a foot of flood water isn't as dangerous as pounding storm surge with wave action.
Good luck.
Thanks Diddle.
