| Area Forecast Discussion National Weather Service Melbourne FL 914pm EDT Tuesday September 27 2022 Marine Issued at 829pm EDT Tuesday September 27 2022 Rainbands associated with approaching Hurricane Ian will increase in coverage and intensity tonight from south to north across the area. Tropical storm force wind gusts in squalls will be possible by daybreak. Conditions will then deteriorate tomorrow morning through the remainder of the week, with Tropical Storm conditions expected across all of the local Atlantic zones. Tropical Storm Warnings remain in effect. Hydrology Issued at 829pm EDT Tuesday September 27 2022 Significant rainfall is expected to spread across the area over the next 24 to 48 hours as Hurricane Ian moves closer to the Florida peninsula. Latest guidance suggests a range of 10-15" with isolated amounts greater than 18" occurring over northern portions of east central FL (areas north of Kissimmee/Melbourne), with southern locations receiving 6-8" with isolated totals in excess of 12". A Flood Watch remains in effect for all of east central Florida. This amount of rainfall will cause major flooding for portions of the area, especially for locations that have already received high rainfall amounts over the past 7 days. Creeks and rivers that are already approaching bankfull will overflow, leading to substantial flooding. Urban locations and low lying areas are especially susceptible, with inundation of major roadways and flooding of structures possible. Levels along the Saint Johns River will continue to rise, with Astor forecast to rise above Moderate Flood Stage and above Lake Harney reaching Minor Flood Stage. It is important to note that higher rainfall totals could cause more substantial rises on the river, with flooding similar to Irma in 2017 a possibility. More "flashy" basins, including the Little Wekiva River and Shingle Creek are also greatly impacted by these high rainfall totals, and could quickly rise well into Moderate Flood Stage in a short window of time. Interests along the river should prepare for major flooding and continue to monitor the latest forecasts for Hurricane Ian.
