As per reports, the US National Weather Service (NWS) has issued a Flood Watch for North Texas, including Dallas County and Denton County, effective from Wednesday afternoon (30 September) at 1600 hours local time (2100 hours UTC) through Friday (02 October) at 0700 hours local time (1200 hours UTC).
• The watch has been prompted by the arrival of deep tropical moisture originating from Hurricane Polo, which is expected to combine with an approaching upper-level disturbance from the west to produce widespread heavy rainfall across the region through Friday (02 October).
• The Flood Watch is in effect for a portion of north-central Texas, covering the following counties: Bosque, Collin, Comanche, Cooke, Coryell, Dallas, Denton, Eastland, Ellis, Erath, Fannin, Grayson, Hamilton, Hill, Hood, Jack, Johnson, Lampasas, McLennan, Mills, Montague, Palo Pinto, Parker, Rockwall, Somervell, Stephens, Tarrant, Wise and Young. Key cities within the watch area include Dallas, Fort Worth, Denton, Waco, Frisco, Allen, Waxahachie, Cleburne, Weatherford, Granbury, Bridgeport, Copperas Cove, Midlothian and Bowie, among others.
• Widespread rainfall totals of two to five inches are expected across the region, with isolated higher amounts of up to eight inches possible, particularly along and west of the Interstate 35 (I-35) corridor.
• The heaviest rainfall is forecast to occur Wednesday night (30 September) into Thursday morning (01 October). An upper-level disturbance from the west, combining with the tropical moisture stream, may act as the principal trigger for heavy downpours and thunderstorms.
• The storm system may also produce a significant change in temperatures. Highs may still reach the mid-90s Fahrenheit on Wednesday (30 September), but the arrival of rainfall and cloud cover will push temperatures down markedly, with highs in the upper 70s to around 80 degrees Fahrenheit forecast from Thursday (01 October) onward. Conditions are expected to remain humid throughout the period.
• South-southeasterly winds with gusts reaching up to 25 miles per hour are forecast to increase across the Dallas–Fort Worth metropolitan area on Wednesday (30 September).
• The NWS has reiterated its ‘Turn Around, Don’t Drown’ road safety guidance in connection with the Flood Watch.
