start your morning in the Palm Beaches and the Treasure Coast.

(00:22):
Today is National Hurricane Prepared in this week and the
National Hurricane Center's twenty twenty five tech improvements are out
and got a lot of good updates here. Technology continues
to advance rapidly, The Hurricane Center continues to make use
of it, and they tweet things every year because of this.
Before diving into the changes this year, just kind of
an update about some of what brought about their changes,

(00:44):
including their biggest upgrade for this year, which has to
do with inland impacts. This story out of Tennessee where
Helene cleanup is continuing seven months later.

Speaker 2 (00:56):
More than fourteen million people vacation in Gatlinburg, tennis See
every year. A lot of them book fishing trips on
Douglas Lake in Dandridge, Tennessee. A lot of fishing tournaments
that were scheduled immediately after Hurricane Helen were postponed until
this spring. Clean up on the lake is about ninety
percent complete. Nearly four million cubic yards of Helene debris
have been removed from all Tennessee waterways.

Speaker 1 (01:18):
Yeah, completely forgotten, right, I mean, talk about what happened.
That's Tennessee. North Carolina actually got the worst of it.
And you're seven months removed, You're still not there that
some of these areas are still completely devastated. I'll give
you an idea if everything breaks right this week, the
renovations actually and I have a place on Beach Mountain

(01:42):
High Salvation Mountain Town anyway in the eastern United States,
and got nailed up there almost at the top of
the mountain, got nailed And maybe this week the work
on our place will be done. Our community had a meeting,
boy sgo. It looks like at best it's going to

(02:03):
be over another year to get all of the work
done in the community from the damage from Helene. And
so hurricanes in are recognizing this is their first change
for this year, this upcoming hurricane season. They're going to
have with the experimental Cone Graphic, a depiction of inline
watches and warnings for the United States. So it'll be

(02:23):
completely color coded everywhere that there is a potential impact
and what those likely impacts are, because again, who would
have thought Helene, is a major hurricane, would have had
a much more devastating impact in the North Carolina Mountains
into the Tennessee Valley area than it did in Florida
where it made landfall. That was the case, and so
that's their single biggest change this year is consideration of

(02:44):
inline risk. Second upgrade US RIP Current Risk Map, So
now you're going to have RIP current risk everywhere that
could be, not just at the point of impact. The
third change updated issuance criteria for potential tropical cyclone advisory products.
Sounds kind of wonky, but the bottom line is says
you might have seen in recent years, you have a

(03:04):
potential tropical cyclone that will be placed on the map
when they think, hey, it's going to happen here within
the next couple of days, they are going to extend
that up to seventy two hours from forty eight hours. Similarly,
the fourth change updates to the forecast advisory product, including
the extension of hurricane force winds. So they used to
project expected hurricane force winds up to forty eight hours out.

(03:26):
Now that's also going to seventy two hours in advance.
The fifth change one that's not of concern to us
on the East coast, but the probabilistic storm surge from
the Hawaiian islands much as it sounds. And then the
sixth change one that people are always among the most
interested in a change to the cone itself. So the

(03:46):
annual update to the track forecast air cone the Hurricane
Center said that they are now three to five percent
more accurate, which means the cone itself will be shrinking
again this year for the Atlantic hurricane season by three
to five percent. By the way, the Pacific on even
more so, they're shrinking that one by five to ten percent.

Speaker 3 (04:06):
All right, We'll just a note here on the Florida Panthers.
They didn't start as well in the second round of
the playoffs, says they did the first round. Couldn't mount
a comeback last night, falling short to the Toronto Maple
Leaves in Toronto five to four. So there they go,
oher and one. Game two will be in Toronto as
well tomorrow night.
