IMAGE COURTESY OF NOAA/NESDIS/STAR. Imelda was a short-lived tropical storm that moved inland over Texas just after it developed. The storm and its remnants meandered inland for a couple of days after landfall and produced historic rainfall totals and devastating flooding over portions of southeastern Texas. 1 Original report dated 29 January. This version corrects landfall pressure in Table 1 and the number of and discussion of fatalities in Texas. Tropical Storm Imelda 2 Tropical Storm Imelda 17–19 SEPTEMBER 2019 SYNOPTIC HISTORY The origins of Imelda can be traced back to a mid- to upper-level trough over the eastern United States. A portion of this trough cut off from the mid-latitudes as a mid- to upper-level low that moved southwestward toward the eastern Gulf of Mexico from 10–12 September and associated shower and thunderstorm activity increased from 12–14 September over the eastern Gulf. A weak surface trough developed on 14 September in the vicinity of the upper low and moved west-northwestward toward the central Gulf. The shower and thunderstorm activity covered a large area and remained disorganized through 15 September as the trough moved from the central to the northwestern Gulf. On 16 September, a broad surface area of low pressure formed as the system approached the Texas coast, and later that night convection became more concentrated near the center of the low.

Program Hurricane Harvey State Mitigation Competition – HUD MID Subrecipient Application/Contract White Oak Bayou Partnership Application Project Title White Oak Bayou Partnership Drainage Improvements Project Summary The White Oak Bayou Watershed has experienced multiple major flooding events in recent years including the Memorial Day Flood (2015), the Tax Day Flood (2016) and Hurricane Harvey (2017). These events have amounted to 84 deaths and over $125.5 billion in damages. Because of the devastation and the need to identify measures to mitigation the impacts of major storm events, Harris County studied nearly 100 previously flooded subdivisions and Harris County Flood Control District identified regional solutions, finding drainage alternatives to mitigate risk to life and safety during future storm events. This Flood and Drainage Activity improves drainage at a regional and neighborhood level by making improvements to flood control facilities and six subdivisions within the White Oak Bayou Watershed.

BLAES NOAA/National Weather Service, Raleigh, North Carolina KRISTOPHER D. WHITE NOAA/National Weather Service, Huntsville, Alabama CHRISTOPHER R. HAIN and CHRISTOPHER J. SCHULTZ NASA Marshall Space Flight Center, Huntsville, Alabama (Manuscript received 3 April 2020; review completed 6 December 2020) ABSTRACT Several historic rainfall and flooding events associated with Atlantic Basin tropical cyclones have occurred in recent years within the conterminous United States: Hurricane Joaquin (2015) in early October over South Carolina; Hurricane Harvey (2017) in late August over southeastern Texas; Hurricane Florence (2018) in September over North Carolina; and Tropical Storm Imelda (2019) in September, again over southeastern Texas. A common attribute of these events includes a dramatic transition from dry soils to exceptional flooding in a very short time. We use an observations-driven land surface model to measure the response of modeled soil moisture to these tropical cyclone rainfall events and quantify the soil moisture anomalies relative to a daily, county-based model climatology spanning 1981 to 2013. Modeled soil moisture evolution is highlighted, including a comparison of the total column (0-2 m) soil moisture percentiles (derived from analysis values) to the 1981-2013 climatological database.

  • Climate Change & Hurricanes
    CLIMATE CHANGE & HURRICANES Climate change is increasing hurricane precipitation, intensifying hurricane winds, and boosting storm surge. Increases in air and ocean temperatures due to climate change are having wide-ranging effects on hurricane precipitation, intensity, and coastal flooding. Warmer temperatures increase the rate of water evaporation from land and sea surfaces, which feeds moisture and energy into storms. Warmer air can hold more moisture, which increases the amount of water available for storms to dump out as rain. Additionally, warming oceans and melting land ice have caused sea level rise, which boosts storm surges, the name for the temporary increase in sea level due to storm conditions. Climate change is worsening hurricane precipitation: • Scientists have identified the fingerprint of climate change on the rainfall during Hurricanes Florence (Reed et al. 2020; Paerl et al. 2019), Maria (Keellings and Ayala 2019; Patricola and Wehner 2018), Irma (Patricola and Wehner 2018), Harvey (Trenberth et al. 2018; Wang et al. 2018; Risser and Wehner 2017; Van Oldenborgh et al. 2017), Sandy (Trenberth et al. 2015), Katrina (Patricola and Wehner 2018; Trenberth et al. 2007), and Tropical Storm Imelda (Van Oldenborgh et al. 2019). Climate change is leading to more intense hurricanes, as measured by wind or central pressure: • In almost every region of the world where hurricanes form, their maximum sustained winds are getting stronger due to human-caused climate change (Kossin et al. 2020). • Climate change is contributing to sea surface temperature increases in the Atlantic and Pacific regions where hurricanes form, increasing the energy available to intensifying storms (Gillett et al.

    Best Practice: Flood Insurance points to brighter future, fosters new plans Release Date: November 22, 2019 AUSTIN, Texas – Maddie and Charles Peddycoart know more about the costs associated with flood recovery than most. In the 19 years they’ve lived in their home in Hamshire, TX — about 60 miles east of Houston and 27 miles southwest of Beaumont — it has been flooded by storms four times: Hurricanes Rita (2005), Ike (2008), Harvey (2017) and Tropical Storm Imelda (2019). Rita and Ike left about 2 inches of water at the ground level of their home; they recovered quickly. But it was Harvey that provided a valuable lesson about the importance of flood insurance and prepared them for what was to come. Harvey, the first hurricane to hit the Texas coast since Ike, left 2 feet of water in their livable space, one level off the ground. “We have a ground floor level that sits on a concrete slab and steps up about 2 feet into the pier and beam level,” said Maddie, a life skills teacher’s aide at Hamshire-Fannett Elementary School. “Our second level [at 13 feet or 2 inches above Base Flood Elevation] sat on treated wood flooring, not on concrete. We had to get in quick to save what we could.” Without insurance, the Peddycoarts faced devastating expenses and a heartbreaking decision. The couple had to use their son’s college fund to help pay for repairs. “We had to make a home again,” the mother of three explained. It was an expensive project.

    Are You Disaster-Ready? What You Need to Know Before Hurricane Season Introduction In 2019, Chubb published a White Paper entitled “Staying Ahead of the Storm: Preparing for Upcoming Hurricane Seasons,” which noted that major hurricanes during the two previous years, 2017 and 2018, caused storm-related damage totaling hundreds of billions of dollars, while at the same time outlining the lessons learned for mitigating hurricane losses in the future. The 2019 hurricane season was not nearly as costly as the previous two. However, hurricanes in 2019 did cause above-average property damage for the fourth year in a row1, highlighting the critical importance of applying risk management lessons learned from year to year. 1 Are You Disaster-Ready?

    Flood Insurance: A Necessary “Luxury” By Sean D.

Photo courtesy of Eric Dowding. hen Hurricane Harvey came, flooding was nothing Wnew to Braeburn resident Eric Dowding. Having lived in Houston with his wife Trang Phan since Hurricane Rita in 2005, he was familiar with hurricanes but did not person- ally experience his first flood until Memorial Day in 2015. His home situated on Brays Bayou in Greater Meyerland had not flooded once since it was built in 1956, so they went into the forecasted flash floods more than a little confident — even by his own admission, “cocky.”1 Their home’s first flood brought in twelve inches of water. But, thanks to flood insurance, “We got a new house out of it. Let’s put it bluntly,” he said in an interview with the University of Houston’s Resilient Houston: Documenting Hurricane Harvey project. He explained, “It damaged all the walls … the original wood floor. So that had to come up. You take out all the sheetrock up to two or three feet above the Eric Dowding and his wife Trang Phan slept on the countertops to line … redo all your walls, all your flooring.

  • 1 Coastal Storms 1. Introduction
    Coastal Storms By John Benson February 2021 1. Introduction Climate science is hard, really hard. That is why I prefer to live in the past. The past is easy, really easy. But this does not help those of you that want or need to forecast what climate change will bring us in the future. However, because of the limitations defined in the first sentence of this post, we must tread carefully into the future. Some future climate changes are easier to predict than others. Based on the recent past, we can be reasonably sure that: Most temperatures will increase Sea levels will rise Many other impacts based on the above two effects will increase But the impacts of the title of this post fall into the “really hard” category, in spite of being dependent on the above first two bullets. I have posted on this subject before. The following is a good summary of what we knew about hurricanes a few years ago. Fire and Storms – Part 2, Rev b: Part 2 of this series is about the more severe hurricanes resulting from environmental changes brought about by climate change. Rev b was posted in July 2019. https://www.energycentral.com/c/ec/fire-and-storms-%E2%80%93-part-2-rev-b The following post, from May 2019, explored a change in weather patterns that appears to increase the severity of hurricane and other major storm’s impacts. Emerging Negative Effects of Climate Change: Climate change is caused by greenhouse gases (GHG), primarily carbon dioxide (CO2) and methane, increasing in the atmosphere.
