This Saturday morning, August 20, 2022, the National Hurricane Center continues to monitor a storm front that will likely dump excessive amounts of rainfall on Gulf areas.
At 700 PM CDT the disturbance was about 350 miles (565 km) south-southeast of the Mouth of the Rio Grande.
The system is moving toward the northwest near 14 mph (22 km/h), and this motion is expected to continue for the next couple of days. On the forecast track, the disturbance is expected to approach the coast of northeastern Mexico on Saturday and make landfall there Saturday night. Maximum sustained winds remain near 35 mph (55 km/h) with higher
gusts.
Slow strengthening is expected through landfall, and the disturbance is forecast to become a tropical storm tonight or Saturday.
It has a high (80 percent) chance of development in the next 48 hours and in the next 5 days.
The estimated minimum central pressure is 1009 mb (29.80 inches).
WIND: Tropical storm conditions are expected to occur in the warning area beginning Saturday afternoon or evening.
RAINFALL: The Potential Tropical Cyclone is expected to produce total rainfall amounts of 3 to 6 inches, with isolated totals of 8 inches, along the eastern coast of Mexico from the northern
portions of the state of Veracruz across the state of Tamaulipas. Rainfall totals of 1 to 3 inches with isolated higher amounts possible across far south Texas.
STORM SURGE: The combination of storm surge and the 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…
Mouth of Rio Grande to Port Mansfield TX…1-2 ft
Surge-related flooding depends on the relative timing of the surge and the tidal cycle and can vary greatly over short distances. For information specific to your area, please see products issued by your local National Weather Service forecast office.
Storm surge could raise water levels by as much as 1 to 2 feet above normal tide levels along the immediate coast of northeastern Mexico near and to the north of where the center makes landfall.
SURF: Swells generated by this system are forecast to affect eastern Mexico and southern Texas this weekend. These swells are likely to
cause life-threatening surf and rip current conditions. Please consult products from your local weather office.
