NOAA's National Weather Service Advanced Hydrologic Prediction
NOAA’s National Weather Service Advanced Hydrologic Prediction Services How to implement the regional map inline frame ©2012 Office of Hydrologic Development/Office of Climate Water and Weather Service 2 Introduction NOAA’s National Weather Service (NWS) provides a wide variety of hydrologic and hydrometeorologic forecasts and information through the web. These web-based resources originate at NWS field, national center, and headquarters offices and are designed to meet the needs of a wide range of users from someone who needs the five-day forecast for a river near his home to the technically advanced water manager who needs probabilistic information to make long-term decisions on allocation of flood mitigation resources or water supply. The NWS will continue to expand and refine all types of web products to keep pace with the demands of all types of users. Hydrologic resources location The NWS Hydrologic resources can be accessed at https://water.weather.gov or by clicking the “Rivers, Lakes, Rainfall” link from https://www.weather.gov. Regional Map – River Observations and River Forecasts Figure 1: National View The regional AHPS map inline frame (or iframe, as it will be referenced throughout the rest of this document), as seen in figure 1, consists of several components: toggles to change which gauge markers display on the map; ESRI map controls; flood status indicators and location-based data view selectors. The starting point, which is available outside of the iframe component, is a national map providing a brief summary to the river and stream location statuses within the continental United States. From this national overview, you can navigate to specific 3 regions – state, Weather Forecast Office (WFO), River Forecast Center (RFC) and Water Resource Region (WRR) – by selecting an option by neighboring drop down menus or clicking on marker images on the map. -
2021 Rio Grande Valley/Deep S. Texas Hurricane Guide
The Official Rio Grande Valley/Deep South Texas HURRICANE GUIDE 2021 IT ONLY TAKES ONE STORM! weather.gov/rgv A Letter to Residents After more than a decade of near-misses, 2020 reminded the Rio Grande Valley and Deep South Texas that hurricanes are still a force to be reckoned with. Hurricane Hanna cut a swath from Padre Island National Seashore in Kenedy County through much of the Rio Grande Valley in late July, leaving nearly $1 billion in agricultural and property damage it its wake. While many may now think that we’ve paid our dues, that sentiment couldn’t be further from the truth! The combination of atmospheric and oceanic patterns favorable for a landfalling hurricane in the Rio Grande Valley/Deep South Texas region can occur in any season, including this one. Residents can use the experience of Hurricane Hanna in 2020 as a great reminder to be prepared in 2021. Hurricanes bring a multitude of hazards including flooding rain, damaging winds, deadly storm surge, and tornadoes. These destructive forces can displace you from your home for months or years, and there are many recent cases in the United States and territories where this has occurred. Hurricane Harvey (2017), Michael (2018, Florida Panhandle), and Laura (2020, southwest Louisiana) are just three such devastating events. This guide can help you and your family get prepared. Learn what to do before, during and after a storm. Your plan should include preparations for your home or business, gathering supplies, ensuring your insurance is up to date, and planning with your family for an evacuation. -
Report of the Governor's Commission to Rebuild Texas

Schwartz, Chairman Elaine Mendoza, Vice Chairman Phil Adams Robert Albritton Anthony G. Buzbee Morris E. Foster Tim Leach William “Bill” Mahomes Cliff Thomas Ervin Bryant, Student Regent John Sharp, Chancellor NOVEMBER 2018 FOREWORD On September 1 of last year, as Hurricane Harvey began to break up, I traveled from College Station to Austin at the request of Governor Greg Abbott. The Governor asked me to become Commissioner of something he called the Governor’s Commission to Rebuild Texas. The Governor was direct about what he wanted from me and the new commission: “I want you to advocate for our communities, and make sure things get done without delay,” he said. I agreed to undertake this important assignment and set to work immediately. On September 7, the Governor issued a proclamation formally creating the commission, and soon after, the Governor and I began traveling throughout the affected areas seeing for ourselves the incredible destruction the storm inflicted Before the difficulties our communities faced on a swath of Texas larger than New Jersey. because of Harvey fade from memory, it is critical that Since then, my staff and I have worked alongside we examine what happened and how our preparation other state agencies, federal agencies and local for and response to future disasters can be improved. communities across the counties affected by Hurricane In this report, we try to create as clear a picture of Harvey to carry out the difficult process of recovery and Hurricane Harvey as possible. -

Of course, afternoon showers and thunderstorms during the summertime Storms in Wilmington are fairly common in the eastern Carolinas. But, did you know that we experienced record rainfall totals, rising rivers, and flooding within our forecast area this meteorological summer Masonboro 6-8 (June – August 2013)? Here’s a recap of what turned out to be quite a wet summer. Buoy Florence, SC received the most rainfall (27.63’’) of our four climate sites during the months The Tsunami 9-12 of June, July, and August. This total was a staggering 12.53’’ above normal for the summer months. In July alone, 14.91’’ of rain fell in Florence. This made July 2013 the wettest Local Hail Study 12-13 month EVER in Florence since records began in 1948! Wilmington, NC received 25.78’’ of rain this summer, which was 6.35’’ above normal. North Myrtle Beach, SC and Lumberton, A Summer of 14 Decision NC received well over 20 inches of rain as well. Support Excess rainfall must go somewhere, so many of our local rivers rose in response to the heavy rain across the Carolinas. In total, 8 of our 11 river forecast points exceeded flood stage this summer. Some of these rivers flooded multiple times; in fact, our office issued 24 river flood warnings and 144 river flood statements from June to August. -

Flood Categories Below Flood Stage - The river is at or below flood stage. Action Stage - The river is still below flood stage or at bankfull, but little if any impact. This stage requires that forecast be issued as a heads up for flood only forecast points. Minor - Minimal or no property damage, but possibly some public threat. Moderate - Some inundation of structures and roads near the stream – some evacuations of people and property possible. Major - Extensive inundation of structures and roads.

Fermi 2 Ufsar
FERMI 2 UFSAR 2.4. HYDROLOGIC ENGINEERING 2.4.1. Hydrologic Description 2.4.1.1. Site and Facilities The Fermi site is located adjacent to the western shore of Lake Erie (Figure 2.4-1). Prior to construction of Fermi 2, the site area was a lagoon separated from Lake Erie by a barrier beach, known as Lagoona Beach, which formed the eastern site boundary. The Fermi 2 preconstruction topography is shown in Figure 2.4-2. The lagoon was connected to Lake Erie by Swan Creek, a perennial stream that discharges into Lake Erie about 1 mile north of the Fermi plant site. The site for Fermi 2 was prepared by excavating soft soils and rock, and constructing rock fill to a nominal plant grade elevation of 583 ft. All elevations refer to New York Mean Tide, 1935. The topography of the developed site as of December 10, 1972, is shown in Figure 2.4-3. Category I structures housing safety-related equipment consist of the reactor/auxiliary building and the residual heat removal (RHR) complex. These structures are indicated in Figure 2.1-5. The plant site is not susceptible to flooding caused by surface runoff because of the shoreline location and the distance of the site from major streams. Plant grade is raised approximately 11 ft above the surrounding area to further minimize the possibility of flooding. Flooding of the site is conceivable only as the result of an extremely severe storm with a storm-generated rise in the level of Lake Erie. Protection of safety-related structures and equipment against this type of flooding is provided through the location, arrangement, and design of the structures with respect to the shoreline and possible storm-generated waves. -
