A lot of the Houston flooding won't even peak until Tuesday

Here are some gauges in the area:

2. Shit's about to get real tomorrow

They are doing a controled release from one of the reservoirs on the west side of town starting at 2 am, and the other a few hours later. This will cause Buffalo Bayou to rise even more than it has from the rain, which is continuing. How much? We don't know.

Of course they have to do this to keep the dams from rupturing in an uncontrolled fashion.

3. The real thing to keep your eyes on is the Brazos river.

It's SW of Houston, but Houston's grown out to meet it. (Houston's mostly in Harris County, but not quite all of it fits.)

It's expected to crest Tuesday at 6 pm and hold that crest for days right at the top of the levees. If the crest is a bit higher than expected, we could have a problem. Currently about 20% of the county's population is under an evacuation notice.

(And hey, my bit of the NOAA map is about to hit the 25" rainfall mark! Woo-hoo! /sarcasm off)

They were hoping that the rain band that's been hitting them wouldn't move that far east so that Buff Bayou would have a bit of room for the additional release water. Sadly, as soon as the guy announced their intent to release the water at 2 am (or perhaps later, inflow permitting) the band shifted.

But Galveston's seen not so much rain these past two days.

4. Here is one of the gauges for the Brazos River

Currently at 38 feet, record is 54.7 feet and it's expected to reach 59 feet (new record) in three days.

5. I believe a voluntary evacuation order was issued

for people living along the Brazos. I know one was issued for part of Rosenberg.
