Looks like a convergence boundary is setting up on-shore just south of Houston again.

that looks a little farther out in the GOM than any models had it at that this time doesn't it?

Checking in. We are still in good shape in the Atascocita Meadows Subdivision. Twice we experienced flooding, which has never happened in 13.5 years we have lived here. During the late afternoon yesterday, it got up to a 1/4 In my yard and last night halfway in our yard. It never got close to our house. We have had lights all through this. Our streets in our subdivision are good free. This has been an amazing event

Just a tad off topic, but this website is great for posting images to the forums... simple and very fast... no cost either..

Small convective cap overland just NW of the CoC.
Diuranal heating of the ground will likely break that by this afternoon.
Could see some convection fire up on the west side of the CoC then.

HOUSTON (AP) — Officials released more water from Houston-area reservoirs overwhelmed by Harvey early Monday in a move aimed at protecting the city's downtown from devastating floods but that could still endanger thousands of homes, even as the nation's fourth-largest city braced for more rain.

The Army Corps of Engineers started the reservoir releases before 2 a.m. Monday — ahead of schedule — because water levels were increasing at a rate of more than six inches (15 centimeters) per hour, Corps spokesman Jay Townsend said. The timetable was moved up to prevent more homes from being flooded, Townsend said.

Meanwhile, officials in Fort Bend County, Houston's southwestern suburbs, late Sunday issued mandatory evacuation orders along the Brazos River levee districts. County officials were preparing for the river to reach major flood stages late Sunday. County Judge Robert Herbert said at a news conference that National Weather Service officials were predicting that the water could rise to 59 feet (18 meters), three feet (90 centimeters) above 2016 records and what Herbert called an "800-year flood level." Herbert said that amount of water would top the levees and carries a threat of levee failure.

looking at some of the pressure reports around the area. 997 is the lowest I can find.

This loop shows the "train" of moisture now moving toward NOLA

That worries me and saw that too. The models are still forecasting more rain tida5y and tomorrow

If Harveys center sits right on the coast could he strengthen again?

Yes, though limited. the enitre center so that all quads have to have unimpeded inflow right around the center.

From what I can tell off the sat loops this am, this area looks to me to be the center of circulation of Harvey..

Like the weather channel was saying, this may gain 5 mph additional strength once offshore, but dry air is definitely being entrained into it. So it may not even gain that much.
