The Great Miami River is flooding, and the level near Troy has already reached it's highest point in half a century.

That's one among several areas in Southwest Ohio and the Miami Valley affected by flooding and high waters.

The Great Miami near Troy was at 16.58 feet Sunday evening. The highest mark of 16.40 feet was recorded June 11, 1958.

Historic numbers, but the marks are not touching those recorded during the Great Flood of 1913, according to Storm Center 7 Chief Meteorologist Jamie Simpson.

Live Doppler 7 Radar is powerful enough to detect rain and storms, and even insects and other 'air traffic'. Because of the incline on Interstate 75 from West Carrollton City to Miamisburg, our radar, located in Germantown, can actually pick up cars and trucks traveling north and southbound on that ...

Have you ever pulled up the radar on your phone or watched on TV and see what appears to be precipitation on radar when the sun is out? 

You may think there is something wrong with the radar, but actually, there is not. You are seeing ground clutter. 

Doppler Radar is so sensitive it can pick up insect and bird migrations and low-level air traffic.

Our Live Doppler 7 Radar, located near Germantown, actually detects traffic on Interstate 75 between Miamisburg and West Carrollton. 

Storm Center 7 Chief Meteorologist Eric Elwell says the reason is because of the elevation change of the interstate between these locations and the position of WHIO’s radar. Because the elevation increases from north to south in this area, the cars actually come into the radar’s detection range. 

The radar sees the cars as very heavy precipitation. Elwell says that during active weather, the Storm Center 7 team can filter out the traffic or “ground clutter” noise so that storms can easily be detected.

Mars is even brighter than Jupiter in the night sky right now.

This month through early August, Mars and Earth happen to be very close. Right now, the two planets are at the second closest point they’ve been in nearly 60,000 years.
