Narrative: If there were a tab asking if I would like to submit this report to the media I would check it.  Maybe then there would be an urgency to correct the problem when weather is impacting the operation and safety is compromised.I was the final controller on final south and severe to extreme (Level 4 and 5) precipitation was moving quickly East-Northeast thru final.  We were conducting simultaneous ILS approaches to Runways 27 and 26L.  During the earlier part of the session; I had a PIREP of heavy rain and smooth ride from a pilot on about a 6 mile final.  I continued conducting instrument approaches but 15-20 minutes into the session; I noticed planes were being taken off the approach and vectored south at 3;000 and 4;000 feet toward the solid line of level 4 and 5 thunderstorms. Two other previous arrivals had been taken westbound away from the airport.  I quickly climbed one to 5;000 and vectored him Northeast bound and handed the aircraft to final center. The other I climbed to 5;000 then 7;000 and vectored westbound and the eastbound.  I found myself out of room to vector as the thunderstorms were closing in and turned the aircraft North then Southeast bound.  Due to inclement weather conditions the pilot's response was slow and aircraft dragged in the turn as I vectored him Southeast bound to try and have divergence. Aircraft X was a conflict with Aircraft Y at 5;000 on the ILS approach to 26L.  SEPARATION WAS LOST (2.8 MILES AND 500 FEET).Not once did one of the two Traffic Management Coordinators (TMCs) or anyone in charge take the initiative to hold aircraft while the weather moved through.  The arrival sector which was feeding was doing On the Job Training Instruction (OJTI) and continued with their operation.  Neither of the two TMCs got up to assist and acted in a reckless; irresponsible and incompetent manner. The arrival controller was never informed when hobby went to 30L and much less got informed when IAH went to east flow.  A similar situation happened earlier in the day as well as yesterday. It is ashamed that safety is compromised even with the equipment and staffing in the TMC unit.  It is ashamed that vital information does not get passed on when our major airports change runway and the 'feeder' controller is last to get the information or none at all.  It is ashamed the ops manager is not present to make sure the resources are being utilized to the fullest to ensure a smooth operation.  It is ashamed that the TMC unit is a debacle.  The past 2 days are a perfect example of it.I ask you respectfully; what are the key requirements for being part of the TMC unit? I think irresponsible and incompetent describe your unit.  Is that what it takes to be an effective TMC at I90?




Synopsis: Houston TRACON (I90) reports of having to vector and climb aircraft off of final due to weather. The reporter stated that they received no help from Traffic Management Unit (TMU) as this developed into a loss of separation.
