Hazardous Weather Outlook For JEFFERSON County, Kentucky
519 AM EST Fri Feb 23 2018 /419 AM CST Fri Feb 23 2018/

   FLOOD WATCH IN EFFECT THROUGH SUNDAY MORNING  

This hazardous weather outlook is for portions of south central
Indiana and Central Kentucky.

 DAY ONE  Today and Tonight.

Moderate to at times heavy rainfall is expected to continue over
portions of southern Indiana and north central Kentucky this morning.
Flooding of low-lying areas is likely during and after the heaviest 
rainfall.

 DAYS TWO THROUGH SEVEN  Saturday through Thursday.

Several rounds of rainfall are likely through Saturday night across 
southern Indiana and portions of central Kentucky. The axis of 
heaviest rainfall looks to be across southern Indiana and west- 
central Kentucky where an additional 2 to 4 inches of rainfall may 
occur through early Sunday morning. Locally higher amounts will be 
possible. This rainfall combined with saturated soils will lead to 
area creeks and streams running high with flooding likely in many 
locations. Therefore a Flood Watch is in effect through Saturday 
night.

Strong to severe thunderstorms are possible Saturday evening and
Saturday night as a cold front sweeps through the region. Damaging
winds and flash flooding will be the primary threats. 

 SPOTTER INFORMATION STATEMENT  

Spotters are encouraged to report rainfall amounts and any flooding.
Spotter activation may be needed Saturday night.

going to 20 to 30 degrees below zero," and to -33 degrees F at
Sandy Hook on 2/11/1899.  In at least one location, "the Kentucky
River, solidly frozen, was possible for team and wagon."
Priddy, UKAWC
