BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Cleveland OH
628 PM EDT FRI JUN 30 2017

The National Weather Service in Cleveland has issued a

* Flash Flood Warning for...
  Cuyahoga County in northeastern Ohio...

* Until 1230 AM EDT Saturday

* At 625 PM EDT, Doppler radar indicated thunderstorms producing
  heavy rain across the warned area. Up to two inches of rain have 
  already fallen. Flash flooding is expected to begin shortly. 
  Several locations have areas of high water from earlier 
  precipitation and two additional rounds of rain will only add to 
  the flooding issues across the county. Several creeks, including 
  Big Creek and West Creek, have seen water rises and water will 
  likely overflow their banks shortly.

* Some locations that will experience flooding include...
  Cleveland, Parma, Lakewood, Euclid, Cleveland Heights,
  Strongsville, Westlake, North Royalton, Solon, Warrensville
  Heights, South Russell, Highland Hills, North Olmsted, Garfield
  Heights, Shaker Heights, Maple Heights, South Euclid, Parma
  Heights, Rocky River, Seven Hills and Broadview Heights.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 1230 AM EDT FOR
CUYAHOGA COUNTY...

At 750 PM EDT, Doppler radar indicated thunderstorms producing heavy
rain across the warned area. Up to three inches of rain have already 
fallen. Additional rain is moving into the county and will allow for 
flooding to continue across the area. Heavy rainfall and flooding 
has allowed for Interstate 480 to be closed east of State Route 176. 
This is in addition to several high water areas across Cleveland, 
Parma, Brooklyn, Garfield Heights, and Maple Heights.

Some locations that will experience flooding include...
Cleveland, Parma, Lakewood, Euclid, Cleveland Heights, Strongsville,
Westlake, North Royalton, Solon, Warrensville Heights, South Russell,
Highland Hills, North Olmsted, Garfield Heights, Shaker Heights,
Maple Heights, South Euclid, Parma Heights, Rocky River and Broadview
Heights.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, urban areas, highways, streets and underpasses as
well as other drainage areas and low lying spots.
