Cristobal was located near latitude 38.9 North, longitude 92.2 West.

36 hours. 
 
Maximum sustained winds are near 30 mph (45 km/h) with higher gusts.

Cristobal transitions to an extratropical cyclone.
 
The estimated minimum central pressure is 992 mb (29.30 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
WIND: Gusty winds are expected tonight and Wednesday over
portions of the Midwest and western Great Lakes as Cristobal
strengthens as an extratropical low.
 
RAINFALL: Cristobal will produce storm total rainfall accumulations
of 2 to 4 inches with local amounts to 6 inches from Arkansas to
the western Great Lakes through Wednesday morning.  This rainfall
may produce flash flooding, and is forecast to produce new and
renewed minor to moderate river flooding across portions of the
lower Missouri and mid to upper Mississippi Valleys. Smaller
streams and rivers across southeast Louisiana, southern
Mississippi, and eastern Arkansas have already begun to rise.
