ALERT Increased Risk of Fire Spread on Saturday

Increased Risk of Fire Spread on Saturday…

There continues to be an increased risk of fire spread on Saturday. Relative humidity values Saturday afternoon will drop to 25 to 35 percent across much of the area. These low relative humidity values will combine with northwest winds around 15 mph with gusts up to 25 mph, and even occasionally as high as 30 mph, temperatures in the mid to upper 60s, and abundant sunshine. These conditions will support the spread of any fires that ignite, which could quickly become difficult to control.

Outdoor burning is strongly discouraged. Be sure to properly extinguish or dispose of any potential ignition sources, including smoking materials such as cigarette butts. Refer to your state’s forest fire management agency for more information on burn restrictions in your local area.

Relative humidity values will be lower on Sunday, generally ranging from 20 to 30 percent, but winds will be much lighter. Burn restrictions may still be in place given the very dry conditions and lack of any recent rainfall.

NASA Launches and Eclipse

ECLIPSE INFO
In Philadelphia, the eclipse will occur from 2:08 p.m. until 4:35 p.m., peaking at 3:23 p.m.


A solar eclipse occurs when the moon comes between the earth and the sun. During a total solar eclipse, the moon blocks the light coming in from the sun and appears to cover up the sun entirely. This will give viewers a glimpse of the sun’s outer atmosphere, known as the corona.

NASA WALLOPS LAUNCHES MONDAY

During the Eclipse today you will be able to see 3 rockets launched from Wallops.

Wallops Flight Facility on Virginia’s Eastern Shore will launch 3 rockets during the solar eclipse to study how Earth’s upper atmosphere is affected when sunlight dims for a moment over part of the planet.

Those rockets will launch at three different times — 45 minutes before the total solar eclipse, during it, and then 45 minutes after the peak local eclipse, and they are expected to reach a maximum altitude of 260 miles. The launch window opens at 2:40 p.m. EDT, with targeted launch times for the three rockets being 2:40 p.m., 3:20 p.m. and 4:05 p.m., but those times are subject to change.

NASA said the three launches are important to gather data on how the sun’s disappearance affects the ionosphere, “creating disturbances that have the potential to interfere with our communications.”
