KEY MESSAGES

Issued at 300 PM EDT Mon Oct 5 2026

- Increasing coverage of showers and occasional lightning storms this week; a Marginal Risk for Excessive Rainfall exists through Wednesday. Minor flooding is possible where heavy rain occurs.

- A Moderate Risk of rip currents continues at east central Florida beaches. Never enter the water alone and always swim near a lifeguard!

- Poor to hazardous beach and boating conditions are expected by mid week as low pressure strengthens offshore; a Small Craft Advisory for portions of the local Atlantic begins Tuesday night.

DISCUSSION

Issued at 300 PM EDT Mon Oct 5 2026

Now-Tonight...The current satellite presentation is very similar to this time yesterday: clouds reaching the I-4 corridor from the west coast of FL as low-level cumulus forms across the remainder of the area. All ECFL locations are dry for now, but that looks to change later this afternoon and evening as storm chances grow. Southerly surface flow will likely delay the westward push of the east coast breeze until mid afternoon. Already, satellite is showing some congested cumulus along the forming breeze, and KMLB/KVRB/KSUA winds have veered east-southeasterly.

Various CAMs suggest isolated to scattered storm coverage along the breeze after 1-2 PM along the I-95 corridor. Later, attention turns toward interior locations as the west and east coast breezes move inland, eventually colliding near I-4. With this additional forcing, plus a weak front settling over the area this evening, coverage of showers and storms is likely to increase after 5-6 PM. Light but persistent westerly steering flow above 700mb suggests rain and storms should push back east toward the Atlantic coast well beyond 8- 9 PM. The risk for lightning and gusty winds is forecast to gradually diminish after sunset, but locally heavy rain will remain possible. Higher rain rates will lead to a quick 1-3" in spots with some indication of locally higher amounts reaching 4"+, especially from the Orlando metro to Cape Canaveral/Melbourne. Much of the area is in a Marginal Risk (level 1 of 4) for Excessive Rainfall today, highlighting the potential for minor flooding. Standing water on roads and in low-lying/urban areas may occur quickly, so take this into account during evening commute times. Avoid flooded roadways!

Drier conditions are forecast overnight but an isolated shower or two cannot be completely discounted along the I-4 corridor and immediate coastline. Temperatures settle into the 70s for most with the coolest spots north of I-4.

Tuesday-Wednesday...A frontal boundary is forecast to stall over top of or just north of the area mid week, helping to prolong an above- average rainfall pattern. Weak upper level ridging with a longwave trough (well north) over the Great Lakes will sustain west- southwesterly flow aloft. Saturated sounding profiles suggest we will stick with a lot of cloud cover for much of this period, with occasional hints of clearing. High moisture content combined with a stalled front leads to the widely advertised 60-85% rain chances each day. Lightning chances may peak earlier in the afternoon and across across southern locations before scattered/numerous showers and associated clouds limit overall instability. Generally speaking, 1-2" of rain is anticipated for much of the area from Tuesday morning through Wednesday night. Pockets of locally higher amounts (2-4") are expected, especially where repeated rounds of rain occur. Increasingly saturated soils and runoff will support local instances of flooding, especially in poor drainage and urban areas. Based on the latest QPF amounts, areas from Orlando/Cape Canaveral northward have a 40% or greater chance at receiving at least 2" of rain through Thursday morning.

Depending on how far the stalled front sinks to the south, northerly winds look to increase along the Volusia Coast Wednesday (gusts 25- 30+ in the afternoon). This will create hazardous surf conditions and elevate the risk for life-threatening rip currents north of Cape Canaveral.

Temperatures will reflect the added clouds/rain especially across the northern half of the area. Near to above normal temps are forecast from Orlando southward on Tuesday with values in the lower 80s across the north. On Wednesday, much of the area only reaches the low to mid 80s, except along the Treasure Coast, which may still push the upper 80s.

Thursday-Sunday...Low pressure over the central Gulf is being monitored for tropical development later this week. Ridging briefly builds over the Midwest, allowing for this area of low pressure to lift north toward the central Gulf Coast by the weekend. As the system moves farther north, it may be able to pull our stationary front with it and gradually reduce rain chances by Saturday or Sunday. However, there is plenty of uncertainty in any one given solution, and maintaining medium to high rain chances through the weekend is warranted for now. Scattered to widespread showers and occasional lightning storms will peak in coverage each day but showers could linger each night (20-40% chance). The threat for locally heavy rain is expected to continue, along with the risk for flooding. Breezy conditions are forecast each afternoon north of I-4 through Friday, expanding to the whole area Saturday as the pressure gradient tightens. Temperatures will fluctuate a bit, based on the location of the front and persistence/coverage of rainfall, but generally, daytime highs in the 80s and lows in the low/mid 70s can be expected.

MARINE

Issued at 300 PM EDT Mon Oct 5 2026

Through tonight...Generally favorable boating conditions this afternoon will continue until showers and storms push offshore tonight. Light winds and seas 1-3 ft.

Tuesday-Friday...Favorable conditions, outside of showers and storms, last through a better portion of Tuesday. Then, along a stalled front near or just north of the waters, an area of low pressure will help to strengthen north-northeasterly winds (15-25 kt) Wednesday. Small Craft Advisory conditions look to develop over the Volusia waters Tuesday night into Wednesday with seas building up to 6-8 ft Wednesday afternoon/evening. Cautionary conditions are possible offshore and south of the Cape to Sebastian Inlet. Waves remain closer to 3-5 ft nearshore south of the Cape. As winds decrease some Friday, seas decline to 3-6 ft across the local Atlantic.

Rain and storm chances will remain above normal through the period, and occasionally gusty winds may accompany a stronger storm.

AVIATION

(00Z TAFs) Issued at 712 PM EDT Mon Oct 5 2026

Weak front is settling into Central Florida this evening, bringing with it a wind shift out of the NW-NE and showers/storms esp for Orlando and Daytona terminals. This activity should continue through the evening, perhaps clipping TIX and MLB by late evening/early overnight before diminishing. Few gusts to 15-25 kt in storms and initial wind shift behind the passing boundary. Also monitoring some occasionally low CIGs (MVFR) at DAB, but guidance is optimistic that these will be infrequent.

On Tuesday, additional showers/storms are expected by afternoon as the front remains over the area. TEMPOs will likely be required in later packages for MCO and many other terminals by mid-late afternoon.

HYDROLOGY

Issued at 300 PM EDT Mon Oct 5 2026

The St Johns River at Astor is forecast to remain in Action Stage through Tuesday. On Wednesday, another rise into Minor Flood Stage is forecast due to increasing rain chances over the basin and a return of northerly winds. The potential exists for flooding at Astor to last into (at least) the first half of next week.
