Morning Roundup: Happy Allison Day edition

Good morning, Houston. It's June 5 — does that date mean anything to you? It should: Six years ago today, Tropical Storm Allison made landfall on the upper Texas coast, bringing with it more than 40 inches of rain in some areas (and all the flooding that went with it). When all was said and done, the damages totaled $5.5 billion, making Allison the most costly tropical storm in U.S. history. Have any memories of that weekend? We know you do — share 'em in the comments.

>> Traffic jam: An accident involving an 18-wheeler and three other vehicles caused a massive traffic tie-up on the Southwest Freeway during the morning rush hour Monday, stopping traffic for more than an hour and a half. The accident happened shortly after 7 a.m. near Weslayan Road, and the traffic jam was the result not only of the accident itself but also of crews' work to separate the big rig and a vehicle that got caught underneath the truck. All the wreckage was cleared away by 8:42 a.m.; though people were injured in the accident, early reports didn't indicate how many or how severe their injuries were.

>> Poll: Most Houstonians OK with illegal immigrants: As discussion continues over a comprehensive immigration reform bill before the U.S. Senate, it's interesting to note — as KPRC did — that the majority of Houstonians support giving illegal immigrants a path to citizenship. In the annual Houston Area Survey by Rice University's Stephen Klineberg, 68.1 percent of Houstonians polled said they support "granting illegal immigrants in the U.S. a path to legal citizenship if they speak English and have no criminal record," while 26.7 percent said they were against doing so and 5.2 percent said they were undecided. "When people are here, Houstonians and Americans are much more likely to say, 'Let's treat them with dignity and respect. At the same time, let's slow down the number of new immigrants coming,'" Klineberg told Channel 2.

>> HPD considering citywide tactical unit?: According to KHOU, Houston police are looking into creating a citywide Tactical Response Unit that would target crime in neighborhoods that have problems with gangs, drugs and violence. There are already tactical units at each HPD substation, but there's not a program in place that would make them work together — though similar units have been created in other cities, and they've been successful. In San Antonio, for example, the city's TRU arrested 3,707 people in the first four and a half months of this year, nearly 500 of them gang members. Details haven't been worked out yet regarding how many officers would serve in the tactical unit or exactly what their assignments would be.

>> Today's weather: As you might have noticed, it didn't end up raining yesterday, despite what the forecasters (and Houstonist) said. So, though we have a 30 percent chance of showers today, we're hoping that's wrong, too — we could use another beautiful afternoon. Expect a high around 91 this afternoon, with a low tonight around 73 (and that rain chance will stick around until tomorrow afternoon, so be prepared).

For now, keep dry with the news ...
