For a depiction of areas at risk, please see the National Weather Service Storm Surge Watch/Warning Graphic, available at hurricanes.gov. This is a life-threatening situation. Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within the next 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 100 AM CDT (0600 UTC), the center of Tropical Storm Cristobal was located near latitude 23.3 North, longitude 90.1 West. Cristobal is moving toward the north near 14 mph (22 km/h), and this general motion is expected to continue for the next couple of days. On the forecast track, the center of Cristobal will move northward over the central Gulf of Mexico today, and will be near the northern Gulf of Mexico coast on Sunday. Cristobal's center is then forecast to move inland across Louisiana late Sunday and Monday. Recent satellite wind data indicate that maximum sustained winds remain near 45 mph (75 km/h) with higher gusts. Slow strengthening is forecast until landfall occurs on the northern Gulf coast. Weakening will begin once Cristobal moves inland late Sunday and Monday. Tropical-storm-force winds extend outward up to 240 miles (390 km) from the center. NOAA buoy 42001, located in the central Gulf of Mexico, recently reported sustained winds of 40 mph (65 km/h) and a wind gust of 45 mph (76 km/h). The estimated minimum central pressure is 998 mb (29.47 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 Ocean Springs MS to Indian Pass FL including Mobile Bay and Pensacola Bay...1-3 ft Indian Pass FL to Aripeka FL...2-4 ft Aripeka FL to Marco Island FL including Tampa Bay...1-3 ft Morgan City LA to the Mouth of the Mississippi River...2-4 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 beginning late Saturday night. Tropical storm conditions are possible within the watch area on Sunday. RAINFALL: Cristobal is expected to produce the following rain accumulations: Through Wednesday morning, for portions of the eastern and central Gulf Coast and the lower Mississippi Valley, rainfall accumulations of 4 to 8 inches, with local amounts to 12 inches, are forecast. Isolated significant river flooding is possible along the central Gulf Coast. Farther north across the Mid-Mississippi Valley, rainfall totals of 2 to 4 inches, with local amounts to 6 inches, are expected. This degree of rainfall is expected to lead to flash flooding and widespread flooding on smaller streams is possible across the Mid-Mississippi Valley. Mexican states of Quintana Roo and Yucatan...Additional 1 to 3 inches, isolated storm totals of 25 inches. Belize, southern parts of Honduras and the Mexican state of Oaxaca...Additional 1 to 3 inches, isolated storm totals of 12 inches. Southern Guatemala, coastal portions of Chiapas, and El Salvador...Additional 2 to 4 inches, isolated storm total amounts of 35 inches dating back to Saturday, May 30th. Rainfall across Southeast Mexico and northern Central America would continue the risk of life-threatening flash floods and mudslides. SURF: Swells generated by Cristobal will affect portions of the northern and eastern Gulf coast during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office. TORNADOES: The potential for a brief tornado or two will gradually evolve Saturday night across far Southeastern Louisiana.

Tropical Storm Cristobal Forecast Discussion Number 18
2020-06-06 04:39:37| National Hurricane Center (Atlantic)
Issued at 1000 PM CDT Fri Jun 05 2020 025 WTNT43 KNHC 060239 TCDAT3 Tropical Storm Cristobal Discussion Number 18 NWS National Hurricane Center Miami FL AL032020 1000 PM CDT Fri Jun 05 2020 The NOAA and Air Force Hurricane Hunters have been investigating Cristobal this evening and they have found that the storm is a little stronger. The pressure has dropped to 998 mb and a combination of flight-level, SFMR, and dropsonde data support a wind speed of about 40 kt. Cristobal continues to have a large and asymmetric appearance with most of the showers and thunderstorms and strong winds to the north and east of the center. The storm is moving northward at a slightly faster pace, about 12 kt. A south to north steering flow between a deep-layer ridge over the western Atlantic and a mid- to upper-level trough over the western Gulf of Mexico should cause Cristobal to continue moving generally northward for the next couple of days. This motion should take the center of the storm across the Louisiana coast by Sunday night. Around the landfall time, a slight turn to the northwest is expected as a mid-level ridge moves across the central and eastern U.S. Overall, the models are in fairly good agreement and only small changes were made to the previous NHC track forecast. This prediction lies near the middle of the guidance envelope. Cristobal will likely continue to slowly strengthen until it makes landfall along the northern Gulf coast in a couple of days. However, the broad structure of the cyclone, dry air on the west side of the system, and moderate wind shear should prevent a significant amount of intensification. The NHC intensity forecast is largely an update of the previous one and is close to the various consensus models. Cristobal is likely to remain a broad and asymmetric storm when it makes landfall. Therefore, users are urged to not focus on the exact forecast path as the associated winds, storm surge, and rainfall will extend well to the east of the center. Key Messages: 1. Damaging and deadly flooding was already occurring in portions of Mexico and Central America. Cristobal is expected to produce additional extreme rainfall amounts for another day or so. The heaviest additional rainfall is expected over far southern Mexico and portions of the Yucatan Peninsula, while also extending along the Pacific coast from Chiapas to Guatemala and El Salvador. This rainfall could cause widespread life-threatening flash floods and mudslides. Refer to products from your local weather office for more information. 2. There is a danger of life-threatening storm surge outside of the Hurricane and Storm Damage Risk Reduction System from the Mouth of the Mississippi River to Ocean Springs, Mississippi, and a Storm Surge Warning is in effect for those areas. Life-threatening storm surge remains possible along the Florida Big Bend and in other portions of southern and southeastern Louisiana where a Storm Surge Watch is in effect. Residents in these locations should follow advice given by local emergency officials. 3. Tropical storm force winds are expected by late Saturday night along the northern Gulf Coast from southeastern Louisiana to the western Florida Panhandle, including metropolitan New Orleans, and a Tropical Storm Warning is in effect for this area. These winds will arrive well in advance of and extend well east of Cristobals center. 4. Heavy rainfall will spread into portions of the Gulf Coast, from east Texas to Florida this weekend into early next week, with areas of flash flooding. Significant flooding will be possible on smaller tributaries, especially where heavier rainfall occurs over portions of Louisiana and Mississippi.

Persons located within these areas should take all necessary actions to protect life and property from rising water and the potential for other dangerous conditions. Promptly follow evacuation and other instructions from local officials. A Storm Surge Watch means there is a possibility of life- threatening inundation, from rising water moving inland from the coastline, in the indicated locations during the next 48 hours. A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area within the next 36 hours. A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, generally within 48 hours. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 1000 PM CDT (0300 UTC), the center of Tropical Storm Cristobal was located near latitude 22.7 North, longitude 90.1 West. Cristobal is moving toward the north near 14 mph (22 km/h), and this general motion is expected to continue for the next couple of days. On the forecast track, the center of Cristobal will move over the central Gulf of Mexico on Saturday, and be near the northern Gulf of Mexico coast on Sunday. Cristobal's center is then forecast to move inland across Louisiana late Sunday and Monday. Maximum sustained winds have increased to near 45 mph (75 km/h) with higher gusts. Slow strengthening is forecast until landfall occurs on the northern Gulf coast. Weakening will begin once Cristobal moves inland late Sunday and Monday. Tropical-storm-force winds extend outward up to 240 miles (390 km) from the center. The minimum central pressure recently reported by the Air Force Hurricane Hunters was 998 mb (29.47 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 Ocean Springs MS to Indian Pass FL including Mobile Bay and Pensacola Bay...1-3 ft Indian Pass FL to Aripeka FL...2-4 ft Aripeka FL to Marco Island FL including Tampa Bay...1-3 ft Morgan City LA to the Mouth of the Mississippi River...2-4 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 beginning late Saturday night. Tropical storm conditions are possible within the watch area on Sunday. RAINFALL: Cristobal is expected to produce the following rain accumulations: Through Wednesday morning, for portions of the eastern and central Gulf Coast and the lower Mississippi Valley, rainfall accumulations of 4 to 8 inches, with local amounts to 12 inches, are forecast. Isolated significant river flooding is possible along the central Gulf Coast. Farther north across the Mid-Mississippi Valley, rainfall totals of 2 to 4 inches, with local amounts to 6 inches, are expected. This degree of rainfall is expected to lead to flash flooding and widespread flooding on smaller streams is possible across the Mid-Mississippi Valley. Mexican states of Quintana Roo and Yucatan...Additional 1 to 3 inches, isolated storm totals of 25 inches. Belize, southern parts of Honduras and the Mexican state of Oaxaca...Additional 1 to 3 inches, isolated storm totals of 12 inches. Southern Guatemala, coastal portions of Chiapas, and El Salvador...Additional 2 to 4 inches, isolated storm total amounts of 35 inches dating back to Saturday, May 30th. Rainfall across Southeast Mexico and northern Central America would continue the risk of life-threatening flash floods and mudslides. SURF: Swells generated by Cristobal will affect portions of the northern and eastern Gulf coast during the next few days. These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
