Live Status
As of Saturday morning, October 10, 2026, Post-Tropical Cyclone Isaias continues north-northwest across central Alabama. The primary organized threats have shifted to residual heavy rainfall and isolated tornadoes on the eastern side of the circulation, plus the approaching Tropical Storm Rachel on the West Coast. SPC’s 1630 UTC Day 1 Convective Outlook maintains a Slight Risk from eastern Georgia into southern and eastern South Carolina. A couple of tornadoes are possible today over that corridor. WPC’s Day 1 Excessive Rainfall Outlook (updated 0748 UTC) holds Moderate Risk across the Southern Appalachians and over portions of Southern California. No tropical storm or hurricane warnings remain for the U.S. Gulf or Atlantic coast.
Hotspot 1 — Eastern Georgia into Western/Southern South Carolina
SPC Slight Risk covers roughly 34,500 square miles and about 3.5 million people, including Savannah, Columbia, Charleston, North Charleston, and Mount Pleasant. Midday analysis places the remnant circulation over central Alabama with a warm front extending eastward to the South Carolina coast. Destabilization in the warm sector supports scattered storms this afternoon. Enlarged hodographs support storm-scale rotation. A couple of tornadoes are possible primarily during the diurnal heating cycle. A Marginal Risk continues tonight as the warm front advances northward, though uncertainty is high.
Restoration read: tornado swaths remain narrow. Staff as local surveys. Damaging wind gusts are possible with stronger cells. The broader water ticket is the continuing rain bands.
Hotspot 2 — Southern Appalachians
WPC Moderate Risk targets upslope regions from northeast Georgia into the Upstate of South Carolina and western North Carolina. Strong upslope flow with residual Isaias moisture supports heavy precip totals in the 3–5 inch range, with maximum totals of 6–10 inches possible across far western North Carolina into the Upstate of South Carolina. HREF and RRFS show high probabilities for 2-, 3-, and 5-inch amounts. Coastal Carolinas retain potential for isolated 5+ inch totals from coastal convergence. Flash flooding, landslides, and river rises are the primary concerns.
Restoration read: this is the main freshwater flood desk today. Wet drywall, extraction, and structural issues from saturated soils. Prioritize high-terrain and poor-drainage areas. Turn around, don’t drown.
Hotspot 3 — Southern California and Rachel
Tropical Storm Rachel is moving northeast at 22 mph toward northern Baja California and the Southern California border. A Tropical Storm Watch is in effect for the Southern California coast from the U.S./Mexico border northward to the San Diego/Orange County line. WPC Moderate Risk covers portions of Southern California as anomalous moisture is drawn northeast. 1–3 inches, locally higher, are forecast, increasing flash and urban flood potential tonight into Sunday. SPC maintains a Marginal Risk for a few severe wind gusts and low-end tornado potential in the Lower Colorado River Valley into south-central Arizona as the system interacts with shear and moisture. Life-threatening surf and rip currents continue.
Restoration read: urban flooding and wind damage over higher terrain are the tickets. Coastal impacts are primarily surf and minor flooding rather than surge. No widespread structural wind damage expected from tropical-storm-force winds.
Pulse table
| Region | Main threats | SPC / NWS / WPC level | Status this morning |
|---|---|---|---|
| Central Alabama / Isaias center | Residual heavy rain, gusty wind | Post-tropical 35 mph; NHC final advisory | Inland NNW at 10 mph |
| Eastern GA / western & southern SC | Brief tornadoes, damaging wind | SPC Slight | Active this afternoon into evening |
| Southern Appalachians (NE GA / W NC / Upstate SC) | Flash flood, 3–10 in possible | WPC Moderate ERO | Upslope heavy rain ongoing |
| Southern California coast / SW | Heavy rain, TS winds possible, surf | TS Watch; WPC Moderate ERO | Rachel approaching tonight |
| Desert Southwest / AZ | Severe wind gusts, isolated tornado | SPC Marginal | Increasing with Rachel interaction |
What this means for restoration teams
Primary exposure is flash flooding and landslides in the Southern Appalachians from residual Isaias moisture, plus isolated tornado and wind damage in the eastern Georgia / South Carolina Slight Risk zone. In Southern California and the Desert Southwest, Rachel drives urban and flash flooding, strong winds over higher terrain, and coastal surf impacts tonight into Sunday. No widespread hurricane-force wind or storm-surge damage is expected on U.S. land from current systems. Claims will be water-dominant with localized wind/tornado tickets. Stage extraction crews for the Appalachians and monitor San Diego for tonight’s rain onset.
