Although strong winds can sometimes threaten cell towers, most are strong enough to handle the worst that even a Category 5 hurricane can bring. Fire, however, complicates the issue.
When the fires get too close to cell sites, they will obviously burn equipment, antennas, and feedlines. In extreme cases, they will also weaken the towers, leading some to collapse. The smoke and flames can also attenuate signals because of the particulate density in the air.
If a tower collapses, cell networks could take months to restore.
Power outages are also a threat to cell phone towers. The Maui disaster has already wiped out power to at least 14,000 homes and businesses in the area, according to PowerOutage.us. Many towers have backup power generators, but they have limited capacity to keep towers running.
Cell towers have back-up technology built in, but this is typically done through optical fiber cables or microwave (wireless) links. However, if something extraordinary happens, such as interaction with rampant fires, these links may experience catastrophic failures and leave cells without a connection to the rest of the world.
And, in an emergency, a spike in call volume can overload the system -- even if people are able to get reception. Even cells that have a good service may experience outages due to the sheer volume of communication happening at once. Everyone in these areas may be trying to contact relatives or the authorities at once, saturating the network and causing an outage. This is easier to correct though and network operators may put in place additional measures to render them operational quickly.

So okay, it is night-time. You smell smoke. People are screaming. Is it a fire? A volcano eruption? World-War III?
You have no bars on your mobile device. Your land-line is dead, and there is no power. What do you do?
Shelter in place? I hope you have planned for a slow and painful cremation.
Instead, grab your ID, your go-kit, and your portable Ham Radio and get the hell outta there!
Once you reach a place of safety, access the National Simplex Frequency (146.520 MHz on 2 meter band), check for traffic, and report your situation.
What? No Ham Radio? Good luck trying to find out what is going on, where to go, and how your loved ones are doing. You may also wait days for rescue, and if you are injured, you may not survive very long on your own.
Join your local Amateur Radio community -- the life you save may be your own!
