1,000-year flood event leaves 200,000 at risk as water crawls north

More than 200,000 residents in Melbourne, West Melbourne, and Palm Bay faced life-threatening flash flooding on November 2. The event was classified as a 1-in-1000-year occurrence, but the immediate danger has not passed. Meteorologist Jessie Schaper with the National Weather Service office in Melbourne warns that river flooding may persist for several weeks. The floodwater is moving northward through the St. Johns River Basin, threatening major cities including Jacksonville.

The Melbourne NWS Office issued a Flash Flood Emergency after recording over a foot of rainfall. Schaper noted that her own neighborhood in West Melbourne received about 18 inches of rain. By early Tuesday morning, areas one mile north of Grant-Valkaria and Malabar had accumulated over two feet of precipitation. She stated that while the rain has stopped, the floodwater continues to drain from the affected areas into the St. Johns River. The river drains a large area, so levels will continue to rise as the water flows northward.

Receding water is a slow process in Florida due to the flat terrain. In Melbourne, it took three days for the water to recede. Standing water may remain in Palm Bay and Grant-Valkaria for a longer period. Schaper explained that the water simply relocates to the lowest ground levels rather than draining quickly into the ground. Public works crews are currently repairing washed-out roads, but closures may persist. Residents are advised to take alternate routes when commuting.

Schaper emphasized that driving through floodwater is dangerous because depth and road stability are unknown. She recalled seeing cars stranded and submerged during the event. Some roads in the Melbourne and Palm Bay area were completely gone, a fact only confirmed after the water receded. Walking in floodwater is also unsafe due to potential bacteria, downed powerlines, and alligators. Her primary safety reminder is to turn around, not drown.

No formal evacuation orders were issued in Melbourne during the peak of the event. However, law enforcement advised residents to stay in their homes due to road closures. Schaper said that if evacuations are ordered, residents should follow law enforcement recommendations and expect longer travel times. For those in multi-story homes, moving to a higher level may be necessary. In some cases, residents were seen evacuating to kitchen countertops when water entered their homes. Schaper reported that floodwater came within a quarter of an inch of seeping into her own home.

Residents are encouraged to check if they live in a flood zone, as major events can occur even in areas not typically designated as such. Storing water, flashlights, and necessities on higher ground is recommended. Schaper advised monitoring water intrusion from garages and exterior doors. Residents can sign up for emergency alerts from Brevard Emergency Management on their phones to receive real-time updates.
