Post-Tropical Cyclone 03L (Cristobal

Cristobal will track across the western Great Lakes. Heavy rain and gusty winds are expected along Cristobal’s track. Flooding is possible in areas that receive the heaviest rainfall. Cristobal made landfall in southeastern Louisiana on Sunday evening. The track of Cristobal or its remnants over Wisconsin will be very unusual. According to the NHC, the post-tropical cyclone is moving toward the north-northeast near 31 mph (50 km/h) and this motion is expected to continue as Cristobal tracks toward Lake Superior and then into Ontario, Canada by Wednesday morning. Maximum sustained winds are near 35 mph (55 km/h) with higher gusts. Some further strengthening is possible as Cristobal fully transitions to an extratropical low. HAZARDS AFFECTING LAND WIND: Winds gusting over 45 mph are expected tonight and Wednesday over Chicagoland and areas adjacent to the western Great Lakes. RAINFALL: Cristobal will produce storm total rain accumulations of 2 to 4 inches, with isolated maximum amounts of 5 inches from southeast Minnesota through much of Wisconsin, the Upper Peninsula of Michigan, and parts of lower Michigan. This rainfall may produce flash flooding, and is forecast to produce new and renewed minor to moderate river flooding across portions of the mid to upper Mississippi Valleys.
