On Friday, crews were installing the dome over in Charlotte County. 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. WINK News now has a dual-pol doppler radar, the most advanced, in Southwest Florida. Switching to radar only mode in the layers menu will update the image every 5 minutes. Doppler radar / satellite mode set to update an image every 15 minutes. Cities include Cape Coral, Fort Myers, Sanibel, Pine Island. Hail is a good reflector of energy and will return very high dBZ values. Weather radar is fixed on Lee County but can be panned /zoomed to different locations. See the latest United States Doppler radar weather map including areas of rain, snow and ice. 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. Now Fort Myers, FL Forecast Today Hourly Daily 80 Home Local Southwest Florida Weather Doppler Radar Radar / Satellite. 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. According to WINK Doppler 3x, on Friday the stage was 11.4 feet. 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). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. It does this by bouncing a microwave signal off a desired target and analyzing how the object's motion has. A Doppler radar is a specialized radar that uses the Doppler effect to produce velocity data about objects at a distance. Tracking Idalia: Share your videos and photos with WINK News. Fort Myers Weather Doppler Radar, Loop, Rain, Storms, Florida. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Army soldier using a radar gun, an application of Doppler radar, to catch speeding violators. National Weather Service Radar for Wink-Am Fort Myers Current Weather Conditions. 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.
