hit hard by covid with low vaccination rates and very high hospitalization rates as well. there is what is called the moraganza levee system meant to protect this parish with a 1 in 100 year storm surge event. of course we have a category 4 forecast at landfall, that particular levee system and flood protection system is set to withstand a category 3 hurricane. so we ll be testing the limits of this particular flood management system. i m cnn meteorologist derek van dam in tarabone parish, back to you. and that wraps this hour. i m kim brunhuber. new day is next with the latest advisory on hurricane ida. please do stay with us.
it approaches the southeastern coast. we already have these outer bands moving in to st. bernard parish. these storms are packing winds up to 50 miles per hour and this is a foreshadow of things to come. the conditions are just going to go downhill as we go through the coming hours. it is still expected to make landfall somewhere around grand isle to houma as a category 4 hurricane, gusts of winds as high as 150. and remember the eyewall replacement cycle could shift the center. so if it tracks a little to the east, because of the eyewall replacement cycle, it could go closer to new orleans. a little farther to the west, it goes closer to oregon city. regardless, we ll see major impacts especially on the east side of the system. that is where you see the worst impacts in the northeast
way of storm surge, flooding, and severe weather. it makes landfall this afternoon as a category 4 hurricane and then quickly loses its intensity as it comes ashore and pushes inland, it goes over the ohio river valley and eventually on in to the mid-atlantic once we get to mid week. in terms of the threats for the coast of louisiana and those in the immediate those affected immediately, i would say the heavy rain and flooding will be the number one threat. then you have the storm surge, the catastrophic winds and then the tornadoes. in terms of the storm surge, i think that it could get up to about 15 feet along the coastline of louisiana. and then you factor in the flooding and those winds, we re going to see wide presented power outages in this area. tyler, thank you so much. and even as hurricane ida barrels toward the gulf coast of louisiana, it was already dealing with skyrocketing covid
totals that could be up to 15, 16 inches in an isolated area above 20 inches, with that kind of wind, this is a very serious storm. it will be one of the strongest storms to hit louisiana since the 1850s and ironically it is scheduled to make landfall on the 16th anniversary of hurricane katrina. tyler mauldin is tracking the hurricane for us. if there is any hope that it would weaken, those hopes were dashed when it in fact strengthened. it looks to be a mondster storm. we ve seen the winds increase and we have a category 4 hurricane, it is moving to the northwest at 15 miles per hour and it is only about 100 to 150 miles offshore of southeast louisiana. i want you to notice this, the recent satellite images make
quadrant, that is where you get the strongest winds, highest surge and biggest tornado potential. this is what the radar will look like later this afternoon going into this evening as it comes ashore. notice the thunderstorms piling up across southeastern louisiana, moving up into mississippi and alabama. on this side as it approaches, the winds will cause the water to pile up and we could see catastrophic storm surge up to 15 feet near the mouth of the mississippi. in terms of the rainfall, when it makes landfall, it will slow down and really rain itself out. where that center goes, we ll see rainfall get up to about a foot in some areas up to 20 and a wide swathe of 4 to 6 inches on into the lower mississippi valley and the tennessee valley and in addition, kim, yeah, we ll see tornadoes there on the east side of the system. i guess the only hope now is that it passes through quickly. tyler mauldin, thank you so much. we ll check back in with you
