  • Tornado Safety Q & A
    TORNADO SAFETY Q & A The Prosper Fire Department Office of Emergency Management’s highest priority is ensuring the safety of all Prosper residents during a state of emergency. A tornado is one of the most violent storms that can rip through an area, striking quickly with little to no warning at all. Because the aftermath of a tornado can be devastating, preparing ahead of time is the best way to ensure you and your family’s safety. Please read the following questions about tornado safety, answered by Prosper Emergency Management Coordinator Kent Bauer. Q: During s evere weather, what does the Prosper Fire Department do? A: We monitor the weather alerts sent out by the National Weather Service. Because we are not meteorologists, we do not interpret any sort of storms or any sort of warnings. Instead, we pass along the information we receive from the National Weather Service to our residents through social media, storm sirens and Smart911 Rave weather warnings. Q: What does a Tornado Watch mean? A: Tornadoes are possible. Remain alert for approaching storms. Watch the sky and stay tuned to NOAA Weather Radio, commercial radio or television for information. Q: What does a Tornado Warning mean? A: A tornado has been sighted or indicated by weather radar and you need to take shelter immediately. Q: What is the reason for setting off the Outdoor Storm Sirens? A: To alert those who are outdoors that there is a tornado or another major storm event headed Prosper’s way, so seek shelter immediately. I f you are outside and you hear the sirens go off, do not call 9-1-1 to ask questions about the warning.

  • Hurricane Knowledge
    Hurricane Knowledge Storm conditions can vary on the intensity, size and even the angle which the tropical cyclone approaches your area, so it is vital you understand what the forecasters and news reporters are telling you. Tropical Depressions are cyclones with winds of 38 mph. Tropical Storms vary in wind speeds from 39-73 mph while Hurricanes have winds 74 mph and greater. Typically, the upper right quadrant of the storm (the center wrapping around the eye) is the most intense portion of the storm. The greatest threats are damaging winds, storm surge and flooding. This is in part why Hurricane Katrina was so catastrophic when bringing up to 28-foot storm surges onto the Louisiana and Mississippi coastlines. A Tropical Storm Watch is when tropical storm conditions are possible in the area. A Hurricane Watch is when hurricane conditions are possible in the area. Watches are issued 48 hours in advance of the anticipated onset of tropical storm force winds. A Tropical Storm Warning is when tropical storm conditions are expected in the area. A Hurricane Warning is when hurricane conditions are expected in the area. Warnings are issued 36 hours in advance of tropical storm force winds. Here are a few more terms used when discussing hurricanes: Eye: Clear, sometimes well-defined center of the storm with calmer conditions. Eye Wall: Surrounding the eye, contains some of the most severe weather of the storm with the highest wind speed and largest precipitation. Rain Bands: Bands coming off the cyclone that produce severe weather conditions such as heavy rain, wind and tornadoes.

  • PROTECT YOUR PROPERTY from STORM SURGE Owning a House Is One of the Most Important Investments Most People Make
    PROTECT YOUR PROPERTY FROM STORM SURGE Owning a house is one of the most important investments most people make. Rent is a large expense for many households. We work hard to provide a home and a future for ourselves and our loved ones. If you live near the coast, where storm surge is possible, take the time to protect yourself, your family and your belongings. Storm surge is the most dangerous and destructive part of coastal flooding. It can turn a peaceful waterfront into a rushing wall of water that floods homes, erodes beaches and damages roadways. While you can’t prevent a storm surge, you can minimize damage to keep your home and those who live there safe. First, determine the Base Flood Elevation (BFE) for your home. The BFE is how high floodwater is likely to rise during a 1%-annual-chance event. BFEs are used to manage floodplains in your community. The regulations about BFEs could affect your home. To find your BFE, you can look up your address on the National Flood Hazard Layer. If you need help accessing or understanding your BFE, contact FEMA’s Flood Mapping and Insurance eXchange. You can send an email to FEMA-FMIX@ fema.dhs.gov or call 877 FEMA MAP (877-336-2627). Your local floodplain manager can help you find this information. Here’s how you can help protect your home from a storm surge.

  • February 2021 Historical Winter Storm Event South-Central Texas
    Austin/San Antonio Weather Forecast Office WEATHER EVENT SUMMARY February 2021 Historical Winter Storm Event South-Central Texas 10-18 February 2021 A Snow-Covered Texas. GeoColor satellite image from the morning of 15 February, 2021. February 2021 South Central Texas Historical Winter Storm Event South-Central Texas Winter Storm Event February 10-18, 2021 Event Summary Overview An unprecedented and historical eight-day period of winter weather occurred between 10 February and 18 February across South-Central Texas. The first push of arctic air arrived in the area on 10 February, with the cold air dropping temperatures into the 20s and 30s across most of the area. The first of several frozen precipitation events occurred on the morning of 11 February where up to 0.75 inches of freezing rain accumulated on surfaces in Llano and Burnet Counties and 0.25-0.50 inches of freezing rain accumulated across the Austin metropolitan area with lesser amounts in portions of the Hill Country and New Braunfels area. For several days, the cold air mass remained in place across South-Central Texas, but a much colder air mass remained stationary across the Northern Plains. This record-breaking arctic air was able to finally move south into the region late on 14 February and into 15 February as a strong upper level low-pressure system moved through the Southern Plains. As this system moved through the region, snow began to fall and temperatures quickly fell into the single digits and teens. Most areas of South-Central Texas picked up at least an inch of snow with the highest amounts seen from Del Rio and Eagle Pass extending to the northeast into the Austin and San Antonio areas.
