When passed Cuba, which could damage Ida a little, there is nothing in the storms path aside from hot tropical waters right up to landfall, which meteorologists recommend could indicate a strong cyclone nears the Louisiana coast by late Sunday or into Monday early morning.
As very warm Gulf waters, plus warm coastal waters, there is little wind shear in the course of Ida to impede climax, while forecasters likewise say that the upper level outflow is also favorable to supporting a significant hurricane.
Siffert of BMS commented, “Some of the warmest water in the Atlantic Basin is right along the northern Gulf Coast. In addition to all the historical storms discussed above that have intensified in the Gulf of Mexico, lots of current storms intensified right up until landfall. Offered that the warm waters range from 87– 89 degrees F, there is a concern if any named storm enters these waters that quick intensification can happen. ”
There stays some unpredictability however, albeit mainly to do with the ultimate landfall location and simply how intensee typhoon Ida can end up being.
If Ida heightens particularly quickly in the Gulf it could result in a track even more east and a quicker path to landfall, which some recommend might be a little weaker than a more westerly track.
If Ida heightens more gradually meteorologists recommend the path might be slightly more west, as steering features take longer to pick the storm up, enabling a longer-time for accumulation to happen and possibly a more powerful landfall even more west, with even Texas viewed as possible in this scenario.
It is important to note that the forecast cone is rather broad at this time, with the entire Louisiana coast within it, a shift east or west can bring Texas or Alabama to Florida into the edges of the cone and exactly how Ida heightens over the next day might be crucial in deciding the ultimate course of cyclone Ida over this weekend.
That said, the designs are largely in agreement today and all eyes are on a Louisiana landfalling typhoon, at mid to significant strength, Sunday night into Monday morning.
No matter how the track adjusts, the NHC alerts that, “Ida might be near major cyclone strength when it approaches the northern Gulf coast.”
Modelled strength guidance from Tropical Tidbits can be seen below, which continues to reveal that there are some designs which anticipate storm cyclone Ida being a significant typhoon in the Gulf of Mexico as it heads towards the coast.
Tropical storm Ida formed last night in the Caribbean and has now set a course for the Gulf Coast of the United States, with projection designs suggesting a mid to strong hurricane is likely to make landfall in Louisiana and the NHCs forecast now showing a significant Cat 3 or stronger storm near the shore.Albeit already the ninth named tropical storm of the 2021 Atlantic cyclone season, tropical storm Ida, which anticipate designs concur will end up being typhoon Ida over the Gulf of Mexico, has the potential to be the first to trigger a loss of note for the insurance, reinsurance and insurance-linked securities (ILS) market.
Forecast models are mainly in agreement on the landfall of a hurricane Ida being along the central Louisiana coast area, with New Orleans in the right-hand side of the projection cone.
On strength, there is more variation in the design runs, however in the primary, a Category 2 or stronger cyclone Ida landfall is prepared for and some projections are anticipating rapid increase over the extremely warm waters of the Gulf of Mexico and a possibility of a major hurricane landfall.
Nevertheless, the NHCs newest forecast cone (seen even more down this post) now shows typhoon Ida reaching significant Cat 3 or greater strength prior to its landfall.
Insurance coverage and reinsurance broking group BMS Senior Meteorologist Andrew Siffert commented that, “the market is now taking a look at its first major impact of the season.”
Weve currently seen five named storms make landfall in the United States this year, but Siffert noted that total estimated losses throughout the five called storms are still anticipated to fall under $1 billion in insured losses.
Making a cyclone Ida landfall in Louisiana the initially more significant storm hazard of the 2021 season for insurance providers and their reinsurance or ILS capital partners.
Hurricane Ida, as it is presently, has soaked the Cayman Islands and now heads for a brush with eastern Cuba before the open waters of the Gulf of Mexico lie ahead of it.
Currently continual winds are seen as around 45 miles per hour, with gusts greater at approximately 55 miles per hour, and you can see the most recent forecast track from the NHC listed below.
As we discussed in our upgrade the other day, in which we supplied some excellent modelled analysis from Richard Dixon of Inigo Insurance, we likewise discussed that the rainfall capacity of hurricane Ida will be especially high.
On rainfall the NHC states, “Tropical Storm Ida is likely to bring rainfall quantities of 8 to 12 inches with separated maximum amounts up to 15 inches along the central Gulf Coast Sunday into Monday. This is most likely to lead to flash, metropolitan, little stream, and riverine flooding to the central Gulf Coast.”
As early rains warnings, another aspect that shows the NHCs confidence in the projections of cyclone Ida affecting the US Gulf Coast is the reality that storm surge warnings are currently significant.
The NHC is cautioning of the possibility of storm rise heights of up to 11 feet above sea level for parts of the Louisiana coast at this time, which might be a considerable and destructive impact.
Presently the storm surge projections cover a large area, with the NHC warning of 7 to 11 foot of surge for Morgan City, LA to Ocean Springs, MS consisting of Lake Borgne, and 4 to 7 foot for Rockefeller Wildlife Refuge, LA to Morgan City, LA consisting of Vermilion Bay and the exact same for Ocean Springs, MS to the MS/AL border.
The NHC cautions of an “increasing threat of deadly storm surge” for the coast, in addition to an “increasing risk of dangerous hurricane-force winds” from Sunday onwards, including for the New Orleans city area, which is now under a cyclone watch.

Obviously, at this early phase, with tropical storm Ida yet to intensify into hurricane Ida, its impossible to anticipate how noteworthy a loss this could be for reinsurance, insurance coverage and ils market interests.
With Louisiana the target for landfall right now, there are a large range of scenarios from the numerous millions, to the low billions to double-digits, sources have told us, with the exact landfall area and how extreme hurricane Ida can become type in determining just how big a market loss danger the storm presents.
Louisiana has actually revealed us prior to that significant cyclones can lead to smaller sized market losses than expected if they strike a less inhabited, more rural part of the state, or close to the Texas border.
While a landfall even more east can bring more insured worth into focus and eventually drive higher insurance coverage and reinsurance market losses.
The danger is there. Hurricane Ida is threatening the most noteworthy loss of the 2021 storm season up until now, according to the designs at this time.
This is going to be a weekend where those in catastrophe modelling, or actively managing portfolios of risk such as in disaster bonds, or accountable for buying last-minute or live feline security and hedges such as market loss warranty (ILW) items, might discover they need to remain glued to the tropics.
Insurance, reinsurance and ILS market interests can track establishing typhoon Ida over on our 2021 Atlantic typhoon season page and well upgrade you should a more substantial risk develop.
