That moist air rises and the water vapor condenses, and a large fraction of that water falls as rain. Tropical cyclones can also last a long time; if their motion slows, then a particular region can experience that heavy rainfall for multiple days.</p><p>Even compared to other tropical cyclones, the rain from Harvey has been very hard, and gone for a very long time. On Saturday evening (August 26) into Sunday morning (August 27), an intense band of storms developed to the east of Harvey&rsquo;s center, and lined itself up right over Houston. This is a process known as &ldquo;echo training,&rdquo; in which it appears that the individual thunderstorm cells are like train cars that repeatedly pass over the same spot and bring with them <a href="https://t.umblr.com/redirect?z=http%3A%2F%2Fnaturalhazardscience.oxfordre.com%2Fview%2F10.1093%2Facrefore%2F9780199389407.001.0001%2Facrefore-9780199389407-e-132&amp;t=ZTg3YmFlZTMzYzAyZTU3M2UzNDVhNzM4NDliNTk2ZWU3NjNlZTY3MyxyQTVlOTlWNw%3D%3D&amp;b=t%3A0fAve6ZP2l1ZINS112Dovg&amp;p=http%3A%2F%2Fscifigenerationtv.com%2Fpost%2F164791867033%2Fwhat-made-the-rain-in-hurricane-harvey-so-extreme&amp;m=0" target="_blank">heavy precipitation.</a> </p><p>This precipitation band was producing up to six inches of rain per hour &ndash; an extremely high rate &ndash; and it remained over the Houston metro area for several hours, with a couple more that followed immediately after. One location just southeast of downtown Houston recorded 13.84 inches in just three hours. These rains from Saturday night into Sunday morning initiated the massive flooding in the Houston metro area.</p><figure><a href="https://t.umblr.com/redirect?z=https%3A%2F%2Fcdn.theconversation.com%2Ffiles%2F183696%2Farea14mp%2Ffile-20170829-1557-10d2vmk.png&amp;t=NTE1OWRlNzUyM2E0YjQ0ZjQ4NjMwZDU4ZWEwZjRiNDliYWYyMWYxZSxyQTVlOTlWNw%3D%3D&amp;b=t%3A0fAve6ZP2l1ZINS112Dovg&amp;p=http%3A%2F%2Fscifigenerationtv.com%2Fpost%2F164791867033%2Fwhat-made-the-rain-in-hurricane-harvey-so-extreme&amp;m=0" target="_blank"><img src="https://cdn.theconversation.com/files/183696/width754/file-20170829-1557-10d2vmk.png" alt="" /></a> <figcaption> Image from NOAA&rsquo;s GOES-16 satellite at 9:42 p.m. CDT on August 26, 2017.

Usually, when a tropical cyclone turns poleward from the tropics toward the United States, it will interact with one or more midlatitude weather systems that will send the storm on its way after a day or two. But this August, the jet stream has been positioned well to the north of Texas, so none of these disturbances has approached, and Harvey&rsquo;s center of circulation has barely moved since it made landfall. As a result, across the Texas (and now Louisiana) coast, there have been periods with intense rainfall (in more of the rainbands described above), along with lighter, but still substantial, accumulations.</p><blockquote><a href="https://twitter.com/NOAASatellites/status/902263342244429825" target="_blank"></a></blockquote><figure><a href="https://t.umblr.com/redirect?z=https%3A%2F%2Fcdn.theconversation.com%2Ffiles%2F183699%2Farea14mp%2Ffile-20170829-1590-odgut3.png&amp;t=YzMwNjA5OTM2ZWRmZmNlYTQ2MTFjY2FmMzlkNzg3MjZhMDMwZWIyOSxyQTVlOTlWNw%3D%3D&amp;b=t%3A0fAve6ZP2l1ZINS112Dovg&amp;p=http%3A%2F%2Fscifigenerationtv.com%2Fpost%2F164791867033%2Fwhat-made-the-rain-in-hurricane-harvey-so-extreme&amp;m=0" target="_blank"><img src="https://cdn.theconversation.com/files/183699/width754/file-20170829-1590-odgut3.png" alt="" /></a> <figcaption> Hourly rainfall amounts (in inches) between 8 p.m. CDT Saturday, August 26 to 8 p.m. CDT Monday, August 28, at Harris County Gauge C106_310 Berry Bayou @ Nevada Avenue. This station is located just southeast of downtown Houston. By the morning of Wednesday, August 29, this station had received over 44 inches of rainfall over the previous week. Harris County Flood Warning System </figcaption></figure><p>This combination of unusually high rain rates and long duration has resulted in a very large area with 30 to 45 inches of rain in a few days.</p><p>Those of us who study extreme rainfall and flooding, and those who live in and around Houston, know this area is vulnerable to both very heavy rainfall and destructive and deadly floods. The previous standard-bearer for extreme rainfall in the region was Tropical Storm Allison in June 2001, which produced just over 40" of rain around Houston. But the excessive accumulations were fairly localized. Major floods again occurred on Memorial Day in 2015, and on April 18-19, 2016.</p><p>In the April 2016 event, an intense line of overnight storms produced up to 15" of rain in a few hours, similar to the &ldquo;training&rdquo; rainbands in Harvey. But with Harvey, the area covered by the heavy rainfall has been vastly larger, and the rain has persisted for days. For comparison, in just one day (ending Sunday morning, August 27, 2017) the area covered by rainfall from Harvey exceeding 16" is several times larger than the entire April 2016 flood event, and at least two more days of similar accumulations have followed.</p><blockquote><a href="https://twitter.com/russ_schumacher/status/902016090326405121" target="_blank"></a></blockquote><h2><b>Tornado risks</b></h2><p>To make matters even worse, there were also numerous tornadoes reported as the rainbands came on shore. It&rsquo;s fairly common to have tornadoes occur in association with landfalling hurricanes, but what struck me in this case was that tornado warnings were being issued in the same places that had just received massive amounts of rain.</p><p>My research group has studied the challenges associated with multi-hazard situations, and specifically when the <a href="https://t.umblr.com/redirect?z=http%3A%2F%2Fjournals.ametsoc.org%2Fdoi%2Fabs%2F10.1175%2FWAF-D-15-0084.1&amp;t=Y2UzOTE1ZTBkMTYzYWVmNmVlNTFhMzQ2ZWIyMjg0ZTZiOTAxOGNjYixyQTVlOTlWNw%3D%3D&amp;b=t%3A0fAve6ZP2l1ZINS112Dovg&amp;p=http%3A%2F%2Fscifigenerationtv.com%2Fpost%2F164791867033%2Fwhat-made-the-rain-in-hurricane-harvey-so-extreme&amp;m=0" target="_blank">threats of tornadoes and flash flooding occur</a> in the same place at the same time, as the protective responses to those hazards can be at odds with each other. For people to be under both a tornado and a flash-flood warning at the same time is surprisingly common &ndash; these overlapping warnings occur around 400 times per year on average.</p><p>But this situation was taken to a new extreme during Harvey, when tornado warnings were being issued at the same time that emergency officials were sending messages for people to go to their roofs for safety (rather than risk getting caught in the attic). The heartbreaking (but also heroic) video footage of water rescues speaks to the immense human impact of this multifaceted storm.</p><h2><b>Spot-on forecast</b></h2><p>One final remarkable aspect of Hurricane Harvey&rsquo;s rainfall is how accurate numerical weather prediction models &ndash; and the human forecasters who use them to make official forecasts &ndash; were at highlighting the incredible precipitation accumulations.</p><p>Medium-range forecast models at least a week in advance were showing Harvey stalling out along the Texas coast and producing extreme rainfall. As the event neared, essentially every numerical model was showing accumulations over 25 inches. Often, when meteorologists see models making predictions of events that would be unprecedented, we are rather skeptical of that guidance, because there are no points of reference to compare to. But in this case, the models were in close agreement about the potential for a truly major event, and forecasters saw the gravity of the situation.</p><p>The NOAA Weather Prediction Center, which makes official rainfall forecasts (and rarely includes extreme amounts), on Friday afternoon (August 25) predicted a broad swath of over 20 inches, with isolated areas up to 40". Never before had the Weather Prediction Center issued a &ldquo;high risk&rdquo; of excessive rainfall three days in advance, as usually the uncertainties with forecasting precipitation don&rsquo;t allow enough confidence to do so. In fact, their protocol didn&rsquo;t even allow for such an alert so far in advance! But for Harvey&rsquo;s rainfall, they did this on consecutive days, and with high accuracy, because of the expected extremity of the event. (The primary errors in the rainfall forecasts in advance of the storm is that they placed the maxima a bit southwest of Houston, instead of centered over Houston.)</p><figure><img src="https://cdn.theconversation.com/files/183702/width754/file-20170829-1549-18ouajq.jpg" alt="" /><figcaption> Forecast graphic from the NOAA Weather Prediction Center.
