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.

In inflation- adjusted terms, global economic losses from natural and man-made catastrophes were USD 202 billion last year, up from USD 150 billion in 2019. The US was hardest hit, with large stretches of the East Coast pummelled by hurricanes, wildfires in the west, and the Midwest struck by a record number of convective storms. Australia suffered too, from unprecedented drought, wildfire and storms. Asia suffered deadly and catastrophic floods from monsoon rains. …the 18th highest on sigma records in At 2020 prices, the year ranks ninth highest on sigma records in terms of economic GDP-normalised terms. losses caused by natural catastrophes in any one year.

Hurricane Rita Vs. Laura National Weather Center Meteorologist on the Catastrophic Impact Laura Had on Beci’S Service Territory
Date: September 15, 2020 Contact: Danielle Tilley, Communications Specialist Phone: (337) 463-6221 office (337) 463-2809 fax Hurricane Rita vs. Laura National Weather Center Meteorologist on the Catastrophic Impact Laura Had on BECi’s Service Territory DeRidder — By Cheré Coen - As Hurricane Laura approached the Louisiana coast on Aug. 26, emergency officials urged evacuations because of a possible massive storm surge that could flood Lake Charles and surrounding areas. Because of the threat of flooding at the National Weather Service office, Warning Coordination Meteorologist Roger Erickson headed to an emergency operations center located near the Lake Charles Civic Center. Erickson and others who rode out the storm there in the early hours of Aug. 27 wore masks and social distanced themselves in various offices because of COVID-19, Erickson explained. Erickson landed in a small office on the second floor. “After midnight, I heard creaking sounds behind me like someone was in a rocking chair,” he said. “At first it was once every 10 seconds, then every five seconds, then every second. My boss arrived and he heard it too. We figured that the exterior wall and windows were breathing in and out, trying to blow out.” Not long after, the building’s water ceased, creating unsanitary conditions and causing the air conditioner to fail. “Now, I’m in a room getting hot, walls and windows are creaking,” he related. “There’s no water. Three minutes later, I’m feeling nauseated. I noticed everything on the table was shaking. I thought I was in an earthquake. The whole room was shaking.” What Erickson felt was the result of a Category 4 hurricane blasting into the area with 150 mile-per-hour winds, the strongest hurricane to hit Louisiana since the 1850s.

Hurricane Delta: October 9, 2020 Delta Tracking Toward U.S
Hurricane Delta: October 9, 2020 Delta Tracking Toward U.S. Gulf Coast; Threatens Storm-Weary Region With Life-Threatening Winds, Flooding Rain Hurricane Delta is a Category 3 storm heading for a Gulf Coast landfall later Friday with life-threatening storm surge, damaging winds and rainfall flooding from Louisiana and east Texas to Mississippi. This includes some of the same areas that were ravaged by Hurricane Laura more than a month ago. As expected, Delta intensified again over warmer Gulf of Mexico water Thursday and it appears to be leveling off in strength. Delta’s center is currently about 200 miles south of Cameron, Louisiana, moving north at 10 to 15 mph. Happening Now Rainbands from Delta continue to spread inland and conditions will deteriorate along the Louisiana and upper Texas coasts Friday morning. Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend up to 160 miles from Delta’s center. Current Watches and Warnings A hurricane warning is in effect from High Island, Texas, to Morgan City, Louisiana, including Lake Charles and Lafayette, Louisiana; and Port Arthur, Texas. This means hurricane conditions are expected Friday. A storm surge warning is also in effect from High Island, Texas, to the Pearl River, Louisiana, including Calcasieu Lake, Vermilion Bay and Lake Borgne. This means a life-threatening storm surge is expected, in this case Friday afternoon or early evening. Tropical storm warnings are in effect from Sargent to west of High Island, Texas, and from east of Morgan City, Louisiana, to the mouth of the Pearl River, including New Orleans.

G O V E R N O R G R E G A B B O T T September 30, 2020 The Honorable Donald Trump President of the United States The White House 1600 Pennsylvania Avenue, NW Washington, D.C. 20500 Through: Regional Administrator Tony Robinson FEMA Region 6 Denton, Texas RE: Request for Presidential Disaster Declaration—Major Disaster Dear Mr. President: Under the provisions of Section 401 of the Robert T. Stafford Disaster Relief and Emergency Assistance Act, 42 U.S.C. §§ 5121-5207 (Stafford Act), and implemented by 44 CFR § 206.36, I respectfully request that you declare a major disaster for the state of Texas as a result of Hurricane Laura, which made landfall along the Texas-Louisiana border on August 27, 2020. Beginning August 23, 2020, I took the appropriate action under state law with respect to then- Tropical Storm Laura by directing the execution of the state’s emergency management plan and declaring a state of disaster for 62 Texas counties, including Brazoria, Chambers, Galveston, Hardin, Jasper, Jefferson, Newton, Orange, Sabine, and Shelby counties. On August 24, 2020, Texas received approval for a federal Emergency Declaration ahead of then-Tropical Storms Laura and Marco. Texas is grateful for your decisive action and for our partners at FEMA for quickly granting this federal Emergency Declaration. Pursuant to 44 CFR § 206.36, I have determined that damages caused by Hurricane Laura were of such severity and magnitude that effective response is beyond the capabilities of the state and affected local government, and that supplementary federal assistance is necessary to save lives and to protect property, public health, and safety, or to lessen or avert the threat of a disaster.
