In addition to streaming their feeds online, local TV news broadcasts are available on the radio.
KHOU-11 lists its radio partners as KHJZ 95.7 FM, KIKK 650 AM, KILT 100.3 FM, KRBE 104.1 FM.
KRIV-26 is simulcasting on KSEV 700 AM.
(I’ll update with KPRC-2’s and KTRK-13’s simulcasting partners when I find that info.)
And of course, KTRH 740 AM has been wall-to-wall with excellent Hurricane Rita coverage.
UPDATE: A kindly emailer tells me that KTRK-13 is simulcasting on KUHF 88.7 FM.
