The National Weather Service office in Melbourne, Florida issued a Flash Flood Warning early Sunday morning, November 2, at 4:58 AM EST. The warning is in effect until 8:00 AM EST and currently covers three areas: Brevard County, Florida, and Coconino and Navajo counties in Arizona.
A Flash Flood Warning means flooding is already happening or is about to happen very soon. This is the most serious type of flood alert — it is not a watch or an advisory. It means water could rise quickly, often within minutes, on roads, in low-lying spots, and along small creeks and drainage areas.
What You Might Notice
Residents in the warned areas could see rapidly rising water on streets, water flowing over normally dry washes and low-water crossings, poor drainage in urban neighborhoods, and reduced visibility from heavy rain. In Brevard County — home to Melbourne, Palm Bay, and the Kennedy Space Center area — urban streets and underpasses are the main concern. In Coconino and Navajo counties, which include Flagstaff, Sedona-area terrain, and the Navajo Nation, flash flooding tends to follow desert washes, slot drainages, and burn-scar areas, where runoff can travel miles downstream from where the rain actually fell.
What to Do
First, stay off the roads if you can until the warning expires. Never drive through standing or moving water — just six inches of moving water can knock a person down, and twelve inches can carry away a car. Second, if you live in a low-lying area or near a creek or wash, move to higher ground or an upper floor. Third, in Arizona especially, avoid hiking canyons or camping in washes during this window, even if the sky above you looks clear — storms upstream can send water your way with little warning.
The warning is currently set to expire at 8:00 AM EST, but it can be extended or reissued if heavy rain continues. Keep a phone or weather radio handy for updates.
Data for this alert comes from the National Weather Service (NWS), part of NOAA, via the NWS Melbourne, Florida forecast office.
Frequently Asked Questions
Why does a Florida weather office warn about Arizona counties?
Warnings are listed under the issuing office that generated the bulletin, but each county named — Brevard, FL and Coconino and Navajo, AZ — has its own local threat. Residents should follow guidance from their local National Weather Service office.
What should I do right now if I'm in a warned area?
Avoid driving, especially through flooded roads, and move to higher ground if you're near a creek, wash, or low-lying spot. The warning runs until 8:00 AM EST, so the highest-risk window is the next few hours.
How long will this last?
This specific warning expires at 8:00 AM EST on November 2, but it can be extended or reissued if heavy rain continues. Keep monitoring local NWS updates through the morning.
Is it safe to drive if the road looks only slightly flooded?
No — turn around. As little as six inches of moving water can sweep a person off their feet, and a foot of water can float most vehicles, and the road underneath may be washed out.
