>>In nature, hazardous weather
is almost always in motion.

4
00:00:15,890 --> 00:00:18,977
New research and technology are
making it possible

5
00:00:18,977 --> 00:00:21,438
to provide more continuous
information 

6
00:00:21,438 --> 00:00:24,149
about a storm and
its movement.

7
00:00:24,566 --> 00:00:28,278
Threats in Motion is the next
step in the evolution of how

8
00:00:28,278 --> 00:00:31,239
weather information is provided
to the public.

9
00:00:31,990 --> 00:00:35,869
Let’s take a look at how tornado
warnings are currently issued.

10
00:00:37,203 --> 00:00:40,957
A warning polygon is added to
alert those in harm’s way.

11
00:00:41,166 --> 00:00:44,711
As the storm gets closer to the
edge of the polygon,

12
00:00:44,711 --> 00:00:46,588
a new warning is issued.

13
00:00:46,713 --> 00:00:48,506
Once the storm has passed,

14
00:00:48,506 --> 00:00:50,341
the old warning goes away.

15
00:00:50,592 --> 00:00:54,054
This process is repeated for
the life of the storm.

16
00:00:54,804 --> 00:00:58,475
Now let’s look at how Threats
in Motion works.

17
00:00:58,683 --> 00:01:02,353
A warning polygon is issued at
the location of the threat.

18
00:01:02,729 --> 00:01:06,232
and warning extends out in time
with a thirty minute projection

19
00:01:06,232 --> 00:01:07,567
of the storm's path.

20
00:01:07,859 --> 00:01:10,236
The warning moves in the
same direction

21
00:01:10,236 --> 00:01:13,281
- and at the same rate -
as the storm.

22
00:01:13,698 --> 00:01:16,242
People are alerted as soon
as the warning polygon

23
00:01:16,242 --> 00:01:18,328
includes their location. 

24
00:01:18,787 --> 00:01:21,915
>>Threats in Motion basically takes
the computer power we have

25
00:01:21,915 --> 00:01:23,917
to allow us to update it more
frequently.

26
00:01:24,209 --> 00:01:26,753
Give more frequent updates
and advanced warning

27
00:01:26,753 --> 00:01:29,005
for people who are downstream
rom where the current warnings

28
00:01:29,005 --> 00:01:31,257
are right now and give them
advanced lead time

29
00:01:31,257 --> 00:01:32,300
to take action.

30
00:01:32,801 --> 00:01:36,221
ere’s an example of how Threats
in Motion gives people

31
00:01:36,221 --> 00:01:37,722
more time to react.

32
00:01:38,139 --> 00:01:40,141
Let’s say Jane lives here.

33
00:01:40,433 --> 00:01:41,935
And Hector lives here.

34
00:01:42,435 --> 00:01:44,270
With the traditional warning
polygon,

35
00:01:44,270 --> 00:01:47,732
[Phone vibrates and rings]

Jane gets an alert with plenty
of time to take action.

36
00:01:48,399 --> 00:01:49,901
Hector - on the other hand -

37
00:01:49,901 --> 00:01:53,154
is just outside the warning
polygon and doesn’t get

38
00:01:53,154 --> 00:01:55,448
[Phone vibrates and rings]

the alert until the next
warning is issued.

39
00:01:55,740 --> 00:01:58,368
Hector has less time to
take precautions.

40
00:01:58,618 --> 00:02:02,205
Now compare the same situation
with Threats in Motion.

41
00:02:02,205 --> 00:02:02,539
[Phone vibrates and rings]

42
00:02:02,539 --> 00:02:03,748
With a moving warning,

43
00:02:03,832 --> 00:02:04,707
both Jane and Hector

44
00:02:04,707 --> 00:02:05,583
[Phone vibrates and rings]

both Jane and Hector

45
00:02:05,583 --> 00:02:07,127
receive an equal heads up.

46
00:02:07,919 --> 00:02:11,047
Threats in Motion also will
improve how long you

47
00:02:11,047 --> 00:02:13,383
and your family need to
stay in your shelter.

48
00:02:13,967 --> 00:02:17,428
Notice Jane’s location.Once
the threat moves past her,

49
00:02:17,428 --> 00:02:20,306
she receives an all clear
notification.

50
00:02:20,890 --> 00:02:23,726
>>It’s a better more seamless
way of letting people know

51
00:02:23,726 --> 00:02:25,520
when they’re in the threat area

52
00:02:25,562 --> 00:02:27,355
but almost as importantly
when they’re out of it

53
00:02:27,355 --> 00:02:28,690
and can come out of their
shelter.

54
00:02:29,274 --> 00:02:32,485
>>The way a warning is issued
with Threats in Motion

55
00:02:32,485 --> 00:02:34,028
will affect everyone.

56
00:02:34,237 --> 00:02:36,489
That’s why NOAA researchers
are partnering with

57
00:02:36,489 --> 00:02:38,241
the National Weather Service,

58
00:02:38,241 --> 00:02:39,617
TV broadcasters,

59
00:02:39,617 --> 00:02:41,327
and emergency management.

60
00:02:41,661 --> 00:02:44,581
>>We have to make sure we
understand how end users

61
00:02:44,581 --> 00:02:47,375
such as the public or
businesses can receive

62
00:02:47,375 --> 00:02:49,544
this information and know
what to do with it.

63
00:02:49,544 --> 00:02:51,421
We also have to make sure
we understand

64
00:02:51,421 --> 00:02:53,464
if forecasters are ready for
this because its a

65
00:02:53,464 --> 00:02:54,716
pretty big paradigm shift.

66
00:02:54,716 --> 00:02:56,509
So we have quite a bit of
research ahead of us

67
00:02:56,509 --> 00:02:58,845
to set us up to do
this successfully.

68
