Excessive Heat in Southern California; Tropical Storm Ian Expected to Rapidly Intensify

Excessive heat is possible through Wednesday over southern California. Strong thunderstorms may pose some risk for severe weather across parts of the upper Ohio Valley into the northern Mid Atlantic coast. Tropical Storm Ian is forecast to approach the Florida peninsula at major hurricane strength by midweek, and poses a risk of dangerous storm surge, hurricane-force winds, and heavy rainfall.

NWS Northern Indiana Pedestal Service Life Extension Program (SLEP) September 2022

Beginning September 12th, 2022, the WSR-88D operated by NOAA’s National Weather Service in Syracuse, Indiana (NWS Northern Indiana) will be down for approximately two weeks for an important upgrade. Technicians will refurbish and replace the pedestal, one of the most critical components of the radar, which is necessary for antenna rotation and positioning to capture data in all directions. The components are extremely heavy and will require the radome to be removed by crane and replaced when the work is completed.

Time Lapse From Previous Pedestal Replacements

Check out a time lapse of the radome and pedestal removal and replacement from the NWS Pendleton, OR office to get an idea of what's involved in the process.

The radar and pedestal were designed to last 25 years, and this radar has exceeded its life-span. This activity is necessary to keep the radar functioning for another 20 years or more.

The pedestal refurbishment is the third major project of the NEXRAD Service Life Extension Program, a series of upgrades that will keep our nation’s radars viable into the 2030s. NOAA’s National Weather Service, the United States Air Force, and the Federal Aviation Administration are investing $135 million in the eight year program.

The first project was the installation of the new signal processor and the second project was the refurbishment of the transmitter.

The fourth project will be the refurbishment of the equipment shelters. The Service Life Extension Program will be complete in 2023.
