Area Forecast Discussion
National Weather Service Chicago/Romeoville, IL
819 PM CST Sat Nov 24 2018
.UPDATE...
819 PM CST
Have issued a lake shore warning for Cook County IL as well as
Lake and Porter Counties in Indiana for Sunday night into Monday
morning. Lake levels remain nearly 3 feet above chart datum and
around 1 foot higher than the Halloween storm of 2014 which
flooded north bound lanes of Lake Shore Dr in Chicago. Tough to
say just how bad the lake shore flooding will get, comparing this
set-up to the Oct 2014 event, this event has a more favorable wind
direction and higher lake levels, but the fetch of the strongest
winds will be shorter and the duration of the high winds will be
less. Given the expectation of near storm force onshore winds
Sunday night, there is definitely a potential for flooding making
it to Lake Shore Dr, so have opted to with a warning rather than
an advisory.
