00:00:04,571 --> 00:00:13,646
In late July, a deluge of rain fell over the St. Louis metropolitan are and eastern Kentucky.

2
00:00:13,646 --> 00:00:21,988
The flash flooding resulted in fatalities and widespread damage in both regions.

3
00:00:22,822 --> 00:00:31,865
NOAA satellites monitored the storms that 
produced catastrophic flooding.

4
00:00:34,034 --> 00:00:39,739
GOES-16 watched the development 
of the storm system in near real-time.

5
00:00:39,739 --> 00:00:43,710
The Geostationary Lightning Mapper observed increased lightning

6
00:00:43,710 --> 00:00:47,947
as the series of storms moved across the region.

7
00:00:50,950 --> 00:00:55,588
GOES-16's Advanced Basline Imager measured the amount of 
water vapor in the atmosphere

8
00:00:55,588 --> 00:01:00,193
and cloud top temperatures that help forecasters determine the likelihood of precipitation.

9
00:01:01,528 --> 00:01:11,104
NOAA-20 measured water vapor in the atmosphere, providing data that helped forecasters estimate rainfall.

10
00:01:15,742 --> 00:01:20,413
Scientists use data collected from both satellites 
to produce flood maps

11
00:01:20,413 --> 00:01:25,351
to determine where flooding will likely occur.

12
00:01:25,351 --> 00:01:31,691
These maps help first responders decide
where to send aid.

13
00:01:43,436 --> 00:01:48,374
When storm systems develop with the potential 
to cause flash flooding,

14
00:01:48,374 --> 00:01:52,645
NOAA satellites will be watching.
