HOUSTON (CNN) - Harvey's havoc continued to pour down, three days after the storm rammed Texas as a Category 4 hurricane, unleashing a torrent of rain, turning streets into rivers, and leaving thousands of residents stranded in flooded homes.
Harvey, a tropical storm by Tuesday morning with its eye hovering over the Gulf of Mexico, could still dump up to 15 inches of rain on portions of southeastern Texas and southwestern Louisiana, including the saturated Houston area, where thousands have been rescued and many more still wait for help.
Headed east, the storm was due to dump more heavy rain across both states, worsening the "catastrophic and life-threatening" flooding situation, before making landfall again Wednesday morning, near the Texas-Louisiana border, according to CNN Weather Center.
And the water won't stop rising anytime soon. Swollen rivers in east Texas aren't expected to crest until later this week, and federal officials are already predicting the deadly storm will drive 30,000 people into shelters and spur 450,000 people to seek some sort of disaster assistance.
-- President Donald Trump will head to Texas Tuesday to visit parts of the state battered by Hurricane Harvey over the weekend and to survey relief efforts.
"To the people of Texas and Louisiana, we are 100 percent with you," Trump said Monday, adding that he believes Congress will act quickly to provide disaster-relief funding.
-- Houston's George R. Brown Convention Center had 9,021 evacuees on Monday night, said Bob Mayer, Red Cross disaster program manager. Those who couldn't get a cot were given pillows and blankets to sleep on the floor, Red Cross spokeswoman Betsy Robertson said. Houston Mayor Sylvester Turner said city officials are looking for more shelter space.
-- Houston officials will not ask for immigration status or papers from anyone at any shelter, according to tweets in English and Spanish from the city's verified account.
-- Dallas is preparing to open a mega-shelter at its downtown convention center as the city has been asked to get ready for what could be tens of thousands of evacuees from Harvey. Authorities aim to open the Kay Bailey Hutchison Convention Center Tuesday morning.
--The entire Texas National Guard has been activated.
