Ozarks Feeling Mean Hermine Rains, Flooding
Rainfall up to six inches may create life-threatening conditions in the Ozarks into the weekend as Mean Tropical Rainstorm Hermine unloads over the region.
If it were not for the several inches of rain that fell on the Ozarks the first couple of days of the month, the situation may not be as much of a concern. However, despite a long stretch of nasty heat and skimpy rainfall during August, much of the ground in the Ozarks was very moist before Hermine's arrival.
Persistent downpours will quickly run off into streams and rivers into the weekend from northern Arkansas and eastern Kansas to much of Missouri.
Some of the water ways may not handle the volume of the runoff, leading to flooding and flash flooding.
While the overall mass of the rain will shift slowly eastward and weaken with time, it may not depart some areas before leading to damaging and deadly flooding.
Eastward and northward drifting downpours may affect the metro areas of Kansas City and St. Louis into the end of the week, leading to travel delays and urban flooding problems.
People are urged to avoid camping along streams and low lying areas along rivers through the weekend, or until the danger has passed.
Never drive through flooded roadways.
Report flooding to local authorities as soon as possible so protective barricades can be put in place.
This map is Doppler radar's interpretation of Hermine total rainfall as of Thursday midday, September 9, 2010. The Boston Mountains in northern Arkansas seemed to have received the worst so far in the region.
Rain will fall in some needy areas as well including portions of the lower Mississippi Valley. A large part of this area is in moderate or severe drought.
While the downpours will be more spotty in nature in this area, a few locations may get hit with flash flooding, while others receive enough rain to ease the drought conditions a bit.
While Tropical Rainstorm Hermine is forecast to fizzle out upon reaching the Appalachians later this weekend, its moisture may enhance rainfall in a narrow zone of the mid-Atlantic.

People need to pay close attention to the UV index during this time of year. On a sunny day late in the spring and into the summer, the UV is usually at least an 8, which is very high. Readings over 11 are considered extreme values in which only 10 minutes of full exposure to the sun will produce a sunburn.
