![]() ![]() 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. Hail is a good reflector of energy and will return very high dBZ values. Animated weather radar views for the Tampa Bay area, powered by FOX 13s SkyTower - the first and most powerful television station radar in the nation. 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. Get the latest weather news and forecasts from CNNs meteorologists, watch extreme weather videos, learn about climate change and follow major hurricanes. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Tampa Bay weather forecasts and the power of FOX 13s SkyTower Radar from WTVT right in the palm of your hand Track storms in Florida quickly and easily. Notice the color on each scale remains the same in both operational modes, only the values change. Want a minute-by-minute forecast for Tampa, FL MSN Weather tracks it all, from precipitation predictions to severe weather warnings, air quality updates. 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). Each reflectivity image you see includes one of two color scales. Radar Current and future radar maps for assessing areas of precipitation, type, and intensity Currently Viewing RealVue Satellite See a real view of Earth from space, providing a detailed view. The dBZ values increase as the strength of the signal returned to the radar increases. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Wind direction is W at 9 mph14 km/hwith visibility of 10.00 mi16 km. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). National Weather Service Radar for Tampa Current Weather Conditions Mostly Cloudy in Tampa, temperature is 75☏24☌, dew point 47☏8☌, humidity 37. "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.
