Tropical Weather Moving Closer to Texas and Florida

Harvey's remnant is forecast to regain tropical cyclone strength in the next day or two. Once Harvey starts impacting the Texas coast, up to 10 inches of rain will be possible over the next week. Another disturbance on the southern tip of Florida is not expected to strengthen, but it's slow movement could add up to 7 inches of rain over the next week. Heavy rain may produce flash flooding.

A weak cold front will move slowly across the Red River before sunrise Wednesday, then move south of I-20 into Central Texas by Wednesday afternoon and evening. Scattered showers and storms will occur both ahead and behind the cold front. No severe weather is expected, however, brief heavy downpours could cause brief flooding or at minimum, street flooding at times through the day Wednesday.
A cold front will move into the region Tuesday evening and overnight, bringing better chances for showers and storms to North Texas. The highest chances will be near and north of I-20. Any storms will be capable of producing locally heavy rainfall and strong winds during this period. Chances for scattered thunderstorms will spread to all of North and Central Texas on Wednesday afternoon.
A front will stall to our south Wednesday night and Thursday morning. We will continue to have chances of showers and thunderstorms across all but the northeastern parts of North Texas. In addition to cloud to ground lighting, some storms may produce locally heavy rain.
Here's a look at the forecast for the weekend and early next week! Regardless of Harvey's track this weekend, the main focus for our area should be the potential for very heavy rain and possibly some flooding across Central Texas. Stay tuned as we refine the details in the forecast!

Tornadoes Strike Navarro County
Wednesday, September 5, 2007

Based on eyewitness reports, survey information from emergency management officials, and radar data, it appears that two tornadoes developed in southern portions of Navarro County on the morning of Wednesday, September 5, 2007.

The first tornado developed at approximately 7:42 am. The first damage was observed 6.4 miles south-southeast of the community of Richland. The tornado moved northeast and caused minor tree damage to the west of Highway 14. This tornado will be rated an EF-0 on the Enhanced Fujita scale. Maximum winds were likely in the 70-80 mph range. The path length of the twister was 0.8 miles with an average path width of 40 yards.

The second tornado formed at 7:47 am, roughly 2 miles east-southeast of the first tornado. The first damage was noted along County Road 2410, just north of the Freestone County line. This twister was more significant than the first. It uprooted trees and snapped trunks and large limbs as it moved northeast. The tornado destroyed a barn approximately 1 mile west of Interstate 45 and damaged two metal transmission line towers 1/2 mile west of the Interstate. The tornado dissipated shortly after crossing Interstate 45. Based on the transmission tower and tree damage, as well as damage surrounding these areas, the tornado will be rated a low EF-2 on the Enhanced Fujita Scale. Maximum winds were likely in the 110-120 mph range. The twister path length was 6.1 miles with an average path width of 80 yards.

This event was a reminder to all of us in North Texas that tornadoes can, and do, occur any time of the day and any time of the year. These storms reinforce the need to have a severe weather plan in place and practice it frequently. Furthermore, now is the time to get your NOAA weather radio ready. Weather radios will alert you of hazardous weather...whenever it strikes!
