DISCUSSION AND OUTLOOK ---------------------- At 700 PM CDT (0000 UTC), the center of Tropical Storm Cristobal was located near latitude 29.6 North, longitude 89.8 West. Cristobal is moving toward the north near 7 mph (11 km/h). A turn toward the north-northwest is expected later this evening and tonight, followed by a northward motion Monday night and Tuesday. On the forecast track, the center of Cristobal will move inland across southeastern Louisiana through Monday morning, and northward across Arkansas and Missouri Monday afternoon into Tuesday. Maximum sustained winds remain near 50 mph (85 km/h) with higher gusts. Gradual weakening will begin overnight, and Cristobal is forecast to weaken to a tropical depression on Monday. Tropical-storm-force winds extend outward up to 205 miles (335 km) from the center. A NOAA automated observing station on Dauphin Island, Alabama, recently reported a sustained wind of 45 mph (72 km/h) and a gust to 49 mph (80 km/h), and a Weatherflow site on Ship Island, Mississippi, observed a sustained wind of 37 mph (59 km/h) and a gust to 46 mph (74 km/h). The estimated minimum central pressure based on nearby surface observations is 993 mb (29.32 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Cristobal can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3, WMO header WTNT43 KNHC, and on the web at https://www.hurricanes.gov/text/MIATCDAT3.shtml STORM SURGE: The combination of a dangerous storm surge and the tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... Mouth of the Mississippi River to Ocean Springs MS including Lake Borgne...3-5 ft Morgan City LA to Mouth of the Mississippi River...1-3 ft Ocean Springs MS to Marco Island FL including Mobile Bay, Pensacola Bay, and Tampa Bay...1-3 ft The deepest water will occur along the immediate coast in areas of onshore winds and will likely extend along the coast well to the east of the center. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office. WIND: Tropical storm conditions are expected within the Tropical Storm Warning area along the northern Gulf coast through tonight. RAINFALL: Cristobal is expected to produce storm total rainfall accumulations of 5 to 10 inches across portions of the central to eastern Gulf Coast into the Lower Mississippi Valley, with isolated amounts to 15 inches. Rainfall totals of 2 to 4 inches with local amounts to 6 inches are expected across portions of the Mid to Upper Mississippi Valley and Northern Plains near and in advance of Cristobal. This rainfall will likely lead to flash flooding and widespread flooding on smaller streams across portions of the central Gulf Coast into the Lower Mississippi Valley. New and renewed significant river flooding is possible along the central Gulf Coast and into the Mississippi Valley. TORNADOES: A few tornadoes are possible tonight across eastern Louisiana, southern Mississippi, southern Alabama, and northern Florida. SURF: Swells generated by Cristobal will affect portions of the northern and eastern Gulf coast during the next couple of days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
