NATIONAL WEATHER SERVICE TOLEDO OH
400 PM EST SUN DEC 30 1990

THE NATIONAL WEATHER SERVICE IN TOLEDO HAS ISSUED A
SMALL STREAM FLOOD WARNING EFFECTIVE UNTIL  745 PM EST
FOR PEOPLE IN THE FOLLOWING COUNTY...

IN NORTH CENTRAL OHIO
          ...SANDUSKY

THE SANDUSKY COUNTY SHERIFF'S DEPARTMENT REPORTED THAT SMALL STREAMS
CONTINUED TO RISE THIS AFTERNOON CAUSING MANY FLOODED ROADS. AS THE
TEMPERATURES BEGIN TO FALL LATE THIS AFTERNOON AND EVENING THE LIGHT
RAIN FALLING IN SANDUSKY COUNTY WILL CHANGE TO SNOW. THIS WILL SLOW
THE DRAINAGE INTO THE SMALL STREAMS AND THE WATER LEVELS SHOULD BEGIN
TO LEVEL OFF OR SLOWLY FALL.
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE

CROSS SAFELY.  VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  MOVE TO HIGHER GROUND.

SPECIAL WEATHER STATEMENT
NATIONAL WEATHER SERVICE CLEVELAND OH
205 PM EST SUN DEC 30 1990

THE WINTER WEATHER ADVISORIES THAT ARE IN EFFECT FOR MUCH OF OHIO WILL
BE CANCELLED LATER THIS AFTERNOON.

RAIN CONTINUED TO FALL OVER ALMOST ALL OF OHIO EARLY THIS AFTERNOON.
THE COLD FRONT RESPONSIBLE FOR THE PRECIPITATION WAS MOVING SOUTHEAST
THROUGH SOUTHERN OHIO AND WILL BE ALONG THE OHIO RIVER BY EARLY THIS
EVENING.

COLD AIR WAS POURING INTO THE WESTERN PART OF THE STATE BEHIND THIS
FRONT...AND SHOULD CAUSE THE RAIN TO CHANGE OVER TO FREEZING RAIN IN
THE WEST LATE THIS AFTERNOON BEFORE TURNING TO SNOW THIS EVENING.

THE PRECIPITATION BEHIND THE COLD FRONT IS FAIRLY LIGHT...THOUGH...AND
ACCUMULATIONS OF FREEZING RAIN AND SNOW WILL LIKELY NOT BE AS MUCH AS
WAS PREVIOUSLY THOUGHT. SNOW AMOUNTS OF AN INCH OR LESS ARE LIKELY
THROUGH LATE THIS EVENING. BECAUSE OF THIS...THE WINTER WEATHER
ADVISORIES WILL BE DROPPED LATER THIS AFTERNOON.
