Day 2 Fire Weather Outlook NWS Storm Prediction Center Norman OK 1255 AM CDT Sun Jul 06 2025 Valid 071200Z - 081200Z ...NO CRITICAL AREAS... ...Synopsis... A mid-level ridge should remain in place over the southern Rockies through the day on Monday with a cutoff low off the California coast. The height gradient between these two features is expected to strengthen throughout the day, which may allow for a corridor of stronger surface flow (15-20 mph) with 5-10% RH across portions of southern Nevada. However, confidence in the overlap of this stronger surface flow with receptive fuels is not high. Therefore, will hold off on introducing Elevated highlights at this time. ..Supinie.. 07/06/2025 ...Please see www.spc.noaa.gov/fire for graphic product... Read more

SUMMARY OF WATCHES AND WARNINGS IN EFFECT: A Tropical Storm Warning is in effect for... * South Santee River, SC to Surf City, NC A Tropical Storm Watch is in effect for... * Edisto Beach to South Santee River, SC A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within the next 12 hours A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 12 hours. Interests elsewhere along the southeast coast of the United States should monitor the progress of Chantal. For storm information specific to your area, including possible inland watches and warnings, please monitor products issued by your local National Weather Service forecast office. DISCUSSION AND OUTLOOK ---------------------- At 200 AM EDT (0600 UTC), the center of Tropical Storm Chantal was located near latitude 33.2 North, longitude 78.8 West. Chantal is moving toward the north near 8 mph (13 km/h). A motion toward the north-northwest is expected overnight, followed by a turn to the northeast by the end of today. On the forecast track, the center of Chantal is expected to move across the coast of South Carolina in the next few hours. Recent aircraft and land-based radar velocity data indicate that maximum sustained winds have increased to near 60 mph (95 km/h) with higher gusts. Little change in strength is expected before landfall, with rapid weakening forecast after landfall. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. Within the past hour, Springmaid Pier in South Carolina reported a sustained wind of 47 mph (76 km/h) gusting to 56 mph (90 km/h). The estimated minimum central pressure based on Air Force dropsonde data is 1002 mb (29.59 inches). HAZARDS AFFECTING LAND ---------------------- Key messages for Tropical Storm Chantal can be found in the Tropical Cyclone Discussion under AWIPS header MIATCDAT3 and WMO header WTNT43 KNHC. WIND: Tropical storm conditions are occurring in the warning and should persist through this morning. Tropical storm conditions are possible in the watch area overnight. RAINFALL: Tropical Storm Chantal is expected to produce heavy rainfall across portions of North Carolina through Monday. Storm total rainfall of 2 to 4 inches, with local amounts up to 6 inches, is expected. This would result in an elevated risk for flash flooding. For a complete depiction of forecast rainfall and flash flooding associated with Tropical Storm Chantal, please see the National Weather Service Storm Total Rainfall Graphic, available at hurricanes.gov/graphics_at3.shtml?rainqpf STORM SURGE: The combination of storm surge and tide will cause normally dry areas near the coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide... South Santee, SC to Surf City, NC...1-2 ft For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at5.shtml?peakSurge TORNADOES: Isolated tornadoes are possible today across parts of eastern South Carolina and eastern North Carolina. SURF: Chantal is expected to bring life-threatening surf and rip currents to portions of the coast from northeastern Florida to the Mid-Atlantic states during the next day or so. A depiction of rip current risk for the United States can be found at: hurricanes.gov/refresh/graphics_at3+shtml/?ripCurrents NEXT ADVISORY ------------- Next complete advisory at 500 AM EDT. $$ Forecaster Papin
