.@SylvesterTurner kicking off a press conference at the George R. Brown Convention Center. Updates to follow

Turner says power will not be fully restored for another couple days. And he asks people to stay off the roads at night and not be "fooled" by conditions during the day, when it's warmer.

There are currently 600 people staying at the city-operated shelter/warming center at @GRBCC, which Turner just toured before the presser. It's full at the moment.

If you get power, you should take advantage & boil water while you still can, says @HouPublicWorks director Carol Haddock. She says the boiled water will stay drinkable.

If you don't have power, use bottled water, even for brushing your teeth or washing your face, Haddock says.

Haddock says the city expects to have normal-ish water pressure tomorrow, at which point Houston can "start the path out of the boil water notice." No specific indication of timing yet

.@HoustonFire has responded to 3,300 calls for service during the storm, 75% of which have been emergency medical service calls, @FireChiefofHFD says.

HFD has also responded to 56 structure fires over the last two days, significantly more than usual.

Two Houstonians have died from carbon monoxide poisoning, Chief Peña says.

There has been just one traffic death during the storm, according to @ArtAcevedo. He warns conditions will be rough again tonight.

Houston public health authority David Persse says many warming centers around the city have electricity that residents w/electric-power medical equipment can use. He reminds people to bring their medication to the warming centers, since there won't be any extra supplies.

Persse said there have been "more carbon monoxide poisonings here than I can remember at any point in my career." He says it's easy to miss the early signs, such as headaches. The next symptoms are confusion and an "altered mental status," Persse says.

Turner says he is still asking residents not to drip their faucets in order to help citywide water pressure. He notes that his own pipes burst after the power came back on at his home.
