Looking at the latest HGX composite radar, it's filled with activity. As I write this, it shows a large area of moderate rainfall directly over my part of Fort Bend county. Yet, it is not even sprinkling. Is this effect something unique to the the interaction of tropical systems and Doppler radar? Usually, the HGX composite is dead on with rainfall it is depicting (normal thunderstorms, etc.)

Composite is a sampling of all layers of the atmophere, so it can be quite overdone. I usually stick to base reflectivity for rainfall.
Last Measurable Rainfall: May 21st

I read that the Euro shows an epic rainfall total for a large part of the area. Any details on that? The 12z gfs put out a 35 at my house northwest Harris County!!!


Yeah, the 12Z Euro moves Harvey between HOU and CLL on Thursday!! :shock:

The GFS has Harvey slowly dissipating just east of San Antonio over the course of the next week.

Canadian sees Harvey slipping up the coast as a TS during the week.

If the hurricane is going to dump 36" of rain why no preempt to lower the reservoir level. In the last few years a short storm had caused flooding when the dam overflow and release of water AFTER the storm. Is the TV station forget about the dam?

Which dam are you concerned about? If it's Barker, it's 30' below top of spillway and Addicks is 47' below top of spillway. The sensor at Buffalo Bayou and the Beltway has increased 1' over the past 12 hours.
