This could be interesting as Srain points out. Today and into tonight ( and tomorrow). Could this produce epic numbers for rainfall totals? Please be weather aware,

That type of rain is rare. It has happened in the past like in 1929. Heavy rain like this fell in April 1929 and again in May 1929.

What is the all time daily rainfall record at IAH?

I know model runs are pointless now, but the HRRR is quite interesting... and makes me nervous.

Regarding earlier question on Barker and Addicks dams: Given the recent rainfall impact, the Addicks reservoir (north of I-10) is the fuller of the two. According to the USGS Streamflow website (http://waterdata.usgs.gov/nwis/uv?cb_00 ... 2016-04-18) the current water level is 96.24' and rising. According to a recent US Army CoE presentation (See page 12: http://www.swg.usace.army.mil/Portals/2 ... nal%29.pdf) the Record High Pool was 97.46' on 9March 1992.

This is a bit disconcerting...

A wide swath of moderate rain headed towards Houston from CLL following the more intense band approaching the Gulf. Rivers, creeks, low lying areas remain in peril.

So as the first line drives towards the coast, is that going to allow the atmosphere to 'recharge' and set up a round 2? If so, when would that happen? My wife is stranded in the Med Center and we're trying to figure out if she has a window to get out. Thanks!

I think we're kind of on a watch and see at this point. going moment to moment. I don't think anyone could give you more than a guess about that.

is that the next disturbance near eagle pass there?

I work at BW8 between Westheimer and Richmond. I made it into the office this morning, but only because I leave the house so early. It was only drizzling at the time. I can see the beltway, Rogerdale and Richmond Ave from different points in the bldg. They closed the beltway at Westpark and the feeder road was a mess, both north and south. When I saw they reopened the beltway going south and there was a break in the weather I took that as my opportunity to head home. You can be sure I will check the weather before I head out tomorrow. I read this forum all the time, I knew what everyone was saying, never thought to check the radar or I would've stayed home.

Stay safe everyone!
