The remnants of Edouard stall over north Texas with storm totals reaching 22 inches, driving water rescues in Hardin County, a Red Cross shelter in Livingston, and a new Neches River flood warning. Pennsylvania faces major flooding on Bald Eagle Creek approaching the January 1996 flood of record, while urban flooding hits the Philadelphia corridor. The national wildfire system holds at Preparedness Level 5 with 84 uncontained large fires, and Oregon’s McCully Fire and Washington’s Sinlahekin and Three Queens fires all have evacuations in effect. Hurricane Lowell, a Category 4 south of Hilo, is sending life threatening surf toward Hawaii. CISA adds seven exploited vulnerabilities with a three day remediation clock, and Missouri receives a major disaster declaration for July flooding. EM Morning Brief is your concise daily update on national and state-by-state emergency management news. Produced by Sitch Radio, an EOC Voices podcast.

Good morning, I'm Cedric and

this is your EM Morning Brief

6

for Thursday, September 3, 2026.

7

The remnants of Edouard are the

day's dominant life safety story.

8

The Weather Prediction Center placed the

system about 40 miles southeast of Dallas

9

at 4 o'clock this morning Central time,

with sustained winds near 25 miles an

10

hour and slow weakening to dissipation

expected over the next 24 hours.

11

That was the final public advisory on the

system, but the flood threat is not over.

12

Flood Watches remain in effect

across much of east Texas.

13

An additional 2 to 4 inches of rain

is possible across northeast Texas

14

today, bringing storm totals along

Edouard's path to 5 to 10 inches,

15

with maximum amounts up to 22 inches.

16

Forecasters expect additional

flash flooding, especially in low

17

lying and urban areas, and isolated

moderate to major river flooding.

18

The national wildfire picture

stays at Preparedness Level 5.

19

The National Interagency Coordination

Center's most recent situation report,

20

an official update published about

24 hours ago, counts 84 uncontained

21

large fires burning across nearly 3.94

22

million acres, with 5 new large

fires and 20,245 personnel committed.

23

Year to date the country has recorded

52,626 fires and more than 8.2

24

million acres burned, which is 163

percent of the ten year average for acres.

25

Idaho and Washington lead with

14 large fires each, followed by

26

Montana with 11 and Oregon with 10.

27

In the Pacific, Hurricane Lowell is

a Category 4 storm about 450 miles

28

south of Hilo with maximum sustained

winds near 145 miles an hour.

29

There are no coastal watches or warnings,

but Lowell's swells are already reaching

30

the Hawaiian Islands and forecasters warn

of life threatening surf and rip currents.

31

On the cyber side, CISA added seven

vulnerabilities to the Known Exploited

32

Vulnerabilities catalog yesterday,

covering Sangoma Switchvox, SonicWall

33

SMA1000 appliances, JFrog Artifactory,

Kestra, LiteLLM and Starlette.

34

Five of the seven carry a remediation

due date of Saturday, September

35

5, an unusually short clock for

federal civilian agencies, and four

36

are flagged for forensic triage.

37

There is no active National Terrorism

Advisory System bulletin, no new

38

CDC Health Alert Network notice, and

no State Department travel advisory

39

level change in the last 24 hours.

Federal disaster activity centers on a new

major disaster declaration for Missouri.

Plains through the Ohio Valley into the
