DISCUSSION AND OUTLOOK ---------------------- At 400 PM CDT (2100 UTC), the center of Tropical Depression Cristobal was located near latitude 41.2 North, longitude 91.0 West or along the Mississippi River at the Iowa and Illinois border. The depression is moving toward the north-northeast near 28 mph (44 km/h) and this direction of motion is expected to continue, with some acceleration of forward speed tonight and Wednesday as Cristobal moves toward Wisconsin, Lake Superior, and Ontario. Maximum sustained winds are near 30 mph (45 km/h) with higher gusts. Some strengthening is forecast tonight and early Wednesday as Cristobal becomes an extratropical low. Cristobal will then weaken and become absorbed in a larger synoptic low pressure area Wednesday night. 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 from the mid Mississippi Valley to the western Great Lakes through Wednesday. 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. TORNADOES: A few tornadoes are possible across the Mississippi and Ohio Valleys into tonight.
