Thanks KD. I don't need (or understand!) the full technical aspects, but do understand your explanation. That's exactly the answer I needed. :-D

the above mentioned synopsis is certainly visiable :wink:

As easily as my street floods, I am NOT getting a warm fuzzy looking at that loop srain. Not at all... The 'blob' that appears on the last couple of frames SW of Houston is what I'm looking at. Just a bit more eastern movement and I'm gonna have to put on my flood pants.

Pissing down here under the Bear Creek Dome. Not much electrical activity, but the rain is coming down in wind-blown buckets.

You can see the meso-low over Washington County

very intense rainfall going on right now and it looks like there is more to come. Minor flooding already starting up around here.

update: I have recorded 0.95" of rain in less than 30 minutes with this first round!

I now have 1.55" of rain recorded, and more is yet to come! I could easily end up topping 2-3" today if this continues.

Extremeweatherguy · #293 Postby **Extremeweatherguy** » Sat May 26, 2007 2:50 pm

I am getting the heaviest rainfall yet right now! Also, it is getting quite windy too.

Current rain total = 2.15"

Now, 6 minutes later...2.50" inches!

(0.35" in just 6 minutes! :eek:

HouTXmetro · #294 Postby **HouTXmetro** » Sat May 26, 2007 3:00 pm

seems like the Beltway 8 West corridor and points Northward are getting pouned. Only .24 inches near the Med Center

Extremeweatherguy · #295 Postby **Extremeweatherguy** » Sat May 26, 2007 3:18 pm

Flood watch just issued through Sunday! Up to 3-5" of additional rainfall may fall in some areas over the next 24-36 hours according to the NWS. Beyond Sunday, more watches look likely too.

That's intense! :eek:

Lots of rain has fallen. I expect more later tonight and through Wednesday.

#298 Postby **vbhoutex** » Sat May 26, 2007 3:46 pm

I'm up to at least 2.43"(doesn't always read right) here. We were out in far NW Harris County(Fiarfiled) when it started and came back in via Fry Road, FM 529, Eldridge and Clay and went through some absolutely torrential downpours(I estimate up to 3"/hr rates). Reports of 4"+ in the Copperfield, Bear Creek areas would not be a surprise.

HouTXmetro · #299 Postby **HouTXmetro** » Sat May 26, 2007 4:17 pm

looks like the Gulf Freeway Corridor and the South Belt areas are getting in on the action now... heavy developing rain poised to hit affect the southern portions of Harris County

Extremeweatherguy · #300 Postby **Extremeweatherguy** » Sat May 26, 2007 4:45 pm

My total for the day is now up to 2.72".
