The Operational Significant Event Imagery website includes photos of hurricanes, volcanoes, forest fires, floods and dust storms. The National Weather Service in Brownsville maintains this excellent website containing links to radar and satellite images, computer forecasts, hydrology, climatology, aviation forecasts and more. Here's a site where you can find amazing photographs taken from space of significant events around the world. Pretty much everything you want to know about tropical weather, including hurricanes threatening the South Texas coastline, can be found here. This is the official website of the National Hurricane Center/Tropical Prediction Center. Plan your day and week with detailed weather reports, live alerts. Here you'll find the latest Rio Grande River flow conditions, updated daily. FEATURES: Watch video of your trusted reporters on the scene, and read revealing articles on what's going on in your community. The International Boundary and Water Commission reports the latest information on the levels of Falcon and Amistad Reservoirs on this website. (WTNH) A joint settlement of 45 million has been reached in the civil case of Richard Cox V the City of New Haven, according to New Haven Mayor Justin Elicker. Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall.The National Weather Service in Brownsville maintains this excellent website containing links to radar and satellite images, computer forecasts, hydrology, climatology, aviation forecasts and more. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The higher the dBZ, the stronger the rainrate. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28).

Torrington PD responded to a call of a car and. The dBZ values increase as the strength of the signal returned to the radar increases. (WTNH) A motorcyclist was killed after crashing head first into a sedan in Torrington Saturday night, according to police. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan.
