Many were rescued in the days that followed, in some cases <a href=http://www.businessinsider.com/overwhelmed-journalists-are-jumping-in-to-rescue-those-trapped-by-hurricane-harvey-as-people-are-sending-addresses-and-desperately-looking-for-help-2017-8 > by journalists</a> or <a href=http://www.businessinsider.com/hurricane-harvey-photos-of-people-being-rescued-2017-8 > good samaritans</a> with fishing boats. Tens of thousands of Texas residents, left with nowhere to go, have retreated to temporary shelters. </p><p> "We are expecting over 450,000 potential registers of disaster victims. That is a huge number," Brock Long, who leads the US Federal Emergency Management Agency, said in <a href=https://www.theguardian.com/us-news/live/2017/aug/28/ex-hurricane-harvey-houston-flooded-as-catastrophe-unfolds-in-texas-latest-updates?page=with:block-59a4074fe4b01cebc9e1802b#block-59a4074fe4b01cebc9e1802b > a statement</a> Monday morning. </p><p> Harvey made landfall on Friday as a Category 4 hurricane, a <a href=http://www.businessinsider.com/hurricane-harvey-second-landfall-zombie-hurricane-2017-8 > second landfall</a> as a tropical storm on Wednesday, and has since been downgraded to a tropical depression. </p><p> Harris County, Texas &mdash; home to Houston and about 5 million people &mdash; was a region among the hardest-hit by the storm's flooding. As the the waters <a href=http://www.businessinsider.com/hurricane-harvey-survivors-financial-toll-2017-8 > begin to recede</a>, many are wondering why mandatory or even voluntary evacuation orders weren't issued for the region ahead of the unprecedented storm. </p><p> "We always say, 'Run from water, hide from wind.' When we say that, we mean storm surge, not rain," Harris County Judge Ed Emmett told reporters during <a href=https://twitter.com/NomaanMerchant/status/901195250450014208 >a press conference</a> on August 25. "In this case, we'll have a lot of water, but it's not the kind of water that we would ask people to evacuate from." </p><p> The biggest reason Houston officials didn't tell residents to evacuate was to avoid clogging highways and other roads at dangerous levels. When Hurricane Rita barreled toward Texas in 2005, for example, an exodus of about 3 million people contributed to at least <a href=https://apps.texastribune.org/road-from-rita/taking-on-traffic/?_ga=2.1335153.1138080540.1503942298-1451398362.1503942298 > 73 deaths</a>&mdash; though some have estimated <a href=https://twitter.com/Fahrenthold/status/901994922231910400 >as many as 107</a>&mdash; before the storm. </p><p><figure id="img-865853" class="figure image-figure-image  postload" data-type="img" data-e2e-name="image-figure-image" data-media-container="image" style=""><postload-img data-src="https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-750-563.jpg" data-sizes="(min-width: 960px) and (max-width: 1259px) 640px, (min-width: 1260px) 960px, (-webkit-min-device-pixel-ratio: 2) 50vw, 100vw" data-srcset="https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-160-120.jpg 160w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-320-240.jpg 320w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-480-360.jpg 480w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-640-480.jpg 640w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-750-563.jpg 750w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-960-720.jpg 960w, https://amp.businessinsider.com/images/59a426a46eac40c92c8b50c4-1136-852.jpg 1136w" data-alt="houston flood harvey 4X3" ></postload-img><span class="image-source-caption"><figcaption class="image-caption" data-e2e-name="image-caption">Before and after the floods from Harvey dumped over 2 feet of rain on Houston in three days.</figcaption><span class="image-source" data-e2e-name="image-source">

This is because many people drive into what appears to be shallow water on a roadway, only to be swept away by deceptively strong currents and deeper-than-expected flooding. </p><p> Michael Lowry, a scientist with the University Corporation for Atmospheric Research, underscored this point in <a href=https://twitter.com/MichaelRLowry/status/902000726129471489 >a tweet on Sunday</a>. </p><p> "Evacuation plans are predicated on storm surge, not rainfall flooding," Lowry said. "Rain evacuations difficult to impossible due to forecast limitations." </p><p> In a press conference on Sunday morning, Houston Mayor Sylvester Turner defended his decision not to evacuate residents en masse. </p><p> "You literally cannot put 6.5 million people on the road," Turner said, <a href=http://www.cnn.com/2017/08/27/us/houston-evacuation-hurricane-harvey/index.html > according to CNN</a>. "If you think the situation right now is bad, you give an order to evacuate? You are creating a nightmare." </p><p> Officials in Harris County did ultimately <a href=http://www.thedailybeast.com/houston-told-people-to-stay-for-harvey-now-they-cant-get-out > issue evacuation orders</a> in some areas early Monday morning. But by that point, many people weren't able to comply with them. </p><p> Aisha Nelson, who moved to Houston after Hurricane Katrina devastated her home, talked about her situation from a rooftop in <a href=https://twitter.com/GMA/status/902143972482605057 >a "Good Morning America" live broadcast</a> Monday morning. She said about 30 other people were on the roof with her. </p><p> "It's not going good for us. Across the street, the building is caving in, and it's water everywhere," Nelson said. "We tried to leave, but there was nowhere for us to go ... Please help us. I'm scared." (One of the show's hosts said the program notified the US Coast Guard about Nelson's location.) </p><p><div id="embed-154573" class='postload embed-container twitter-video ' data-type="embed" data-embed-type="raw" data-postload="&#x20;&#x20;&#x20;&#x20;&#x20;&#x20;&#x20;&#x20;&lt;blockquote&#x20;class&#x3D;&quot;twitter-video&quot;&#x20;data-lang&#x3D;&quot;en&quot;&gt;&lt;p&#x20;lang&#x3D;&quot;en&quot;&#x20;dir&#x3D;&quot;ltr&quot;&gt;&amp;quot&#x3B;Please&#x20;help&#x20;us,&#x20;I&amp;&#x23;39&#x3B;m&#x20;scared.&amp;quot&#x3B;&#x20;Houston&#x20;resident&#x20;stranded&#x20;on&#x20;her&#x20;roof&#x20;with&#x20;no&#x20;food,&#x20;water&#x20;asks&#x20;for&#x20;help&#x20;on&#x20;&lt;a&#x20;href&#x3D;&quot;https&#x3A;&#x2F;&#x2F;twitter.com&#x2F;GMA&quot;&gt;&#x40;GMA&lt;&#x2F;a&gt;&#x3A;&#x20;&lt;a&#x20;href&#x3D;&quot;https&#x3A;&#x2F;&#x2F;t.co&#x2F;cWJShLm5CW&quot;&gt;https&#x3A;&#x2F;&#x2F;t.co&#x2F;cWJShLm5CW&lt;&#x2F;a&gt;&#x20;&lt;a&#x20;href&#x3D;&quot;https&#x3A;&#x2F;&#x2F;t.co&#x2F;xrGNYBzMpy&quot;&gt;pic.twitter.com&#x2F;xrGNYBzMpy&lt;&#x2F;a&gt;&lt;&#x2F;p&gt;&amp;mdash&#x3B;&#x20;Good&#x20;Morning&#x20;America&#x20;&#x28;&#x40;GMA&#x29;&#x20;&lt;a&#x20;href&#x3D;&quot;https&#x3A;&#x2F;&#x2F;twitter.com&#x2F;GMA&#x2F;status&#x2F;902143972482605057&quot;&gt;August&#x20;28,&#x20;2017&lt;&#x2F;a&gt;&lt;&#x2F;blockquote&gt;&#x0A;&lt;script&#x20;async&#x20;src&#x3D;&quot;&#x2F;&#x2F;platform.twitter.com&#x2F;widgets.js&quot;&#x20;charset&#x3D;&quot;utf-8&quot;&gt;&lt;&#x2F;script&gt;&#x20;&#x20;&#x20;&#x20;" data-e2e-name="embed-container" data-media-container="embed"></div></p><p> The full extent of Harvey's devastation is not yet known, though dozens of people have died. </p><p> More than 50 Texas counties have declared a state of disaster, and some groups think the storm's damage <a href=http://www.businessinsider.com/hurricane-harvey-economic-impact-2017-8 > may exceed</a> that of Hurricane Katrina, which totaled <a href=http://www.businessinsider.com/most-destructive-hurricanes-in-us-history-2017-8 > more than $100 billion</a>. </p></div>
