This is always hard to say as the group that stays has a very different make up than those who choose to leave. So you cannot compare the different groups directly.

The first evacuee was rushed into Memorial Regional Hospital’s emergency room around 3 a.m. on Wednesday, escaping a nursing home that had lost air conditioning in the muggy days after Hurricane Irma splintered power lines across the state. Another arrived at 4 a.m. After a third rescue call, at 5 a.m., hospital staff were concerned enough to walk down the street to see the facility for themselves. What they found was an oven. The Rehabilitation Center at Hollywood Hills needed to be evacuated immediately. Fire and rescue units were hurrying the nursing home’s more than 100 residents out. Dozens of hospital staff converged on the area, establishing a command center outside, where workers set up equipment designed for a multi-casualty incident like a bus crash. Red wristbands went to patients with life-threatening conditions, yellow and green for those in better shape.

The police and state authorities were conducting a criminal investigation into the deaths, according to Chief Sanchez and the governor’s office. Witness accounts suggested that the heat had caused problems inside the nursing home at least since Tuesday afternoon. When Eli Pina went to visit her mother, Mirelle Pina, 96, on Tuesday at noon, it was sweltering inside, she said.

In many ways, the extended forecast of Hurricane Irma was an extraordinary triumph for weather prediction technology, with major global modeling systems (e.g., US GFS, European Center, Canadian, UKMET) suggesting a major threat to Florida a week or more out. Even a decade ago, we could not have done this well.

Although the European Center solution was clearly superior, both U.S. and EC forecasts are very good....showing the threat to the U.S. more than a week ahead of time and predicting a sharp right turn days before. Other major modeling systems, such as the United Kingdom and Canadian models, did the same thing. Predicting the exact location of the right turn days ahead is simply beyond the science at this time and may always be, but the models were all excellent in predicting that such a turn would occur in the vicinity of Florida.

•The ability of the U.S. to forecast hurricanes has clearly improved. Congratulations.
•Five years after Hurricane Sandy, the U.S. has not caught up to the European Center, with both improving at roughly the same rate. We need to do better.
•The European Center does a better job at assimilating a wide variety of observations and their model has better physics (e.g., descriptions of moist processes) than the U.S. models--we need to up our game. The proposed new U.S. modeling system (FV-3) is not going to fix these areas.
•The U.S. has spent large amounts of money on hurricane models (e.g., HWRF and now HMON), but in many ways they are inferior to a coarser global model (EC), particularly for track forecasts.
•A clearly deficient hurricane model has recently been developed (for reasons that are not clear)...HMON. It is not ready for prime time, so why show it?
•There was a lot of confusion about which side of Florida would be hit by Irma. Much of this confusion can be traced to inadequate communication by the National Weather Service and the media, with substantial misunderstanding of ensemble prediction by the lay community. We need to do much better in this domain (more in a future blog).
•National Weather Service verification of model quality and hurricane forecast skill is very poor. Why do we have to depend on an innovative professor (Brian Tang), and unofficial web sites (e.g., weathernerds) to supply such information?

I am not knowledgeable in weather forecasting, but is weather modeling an Olympic event? If the results of the European model are available, why are there competing models? Is hemispheric pride at stake? If money is spent on refining models, why not more collaboration? (granted that competition is often healthy...)

If you ask me, all these models look pretty good, but more refined models will always be appreciated.....

The IFS is a global model that runs every twelve hours. Its output runs out to fifteen days in one-day intervals (although output is only made available to most members of the public out to 7 to 10 days, depending on the variable).
-------------snip------------
Because the IFS only offers output on a day-by-day interval, each individual ECMWF member country typically runs its own synoptic-scale forecast for the shorter ranges of 5 days or less, separate from the IFS, with smaller time intervals (examples include the French ARPEGE, British Unified Model and German GME/ICON).
In contrast to the GEM/GDPS (which is copyrighted but freely licensed) and the GFS (which is public domain), the ECMWF's proprietary data and forecasts are heavily restricted and require a licence for most output. A limited amount of the IFS's output is released freely to the public and licensed under a Creative Commons licence that prohibits commercial usage or derivative works.
