A pair of heavy thunderstorms two days apart brought flashbacks to Hurricane Harvey and isolated flooding to parts of Alvin and Manvel last week.
The first storm Tuesday night brought heavy lightning and close to 2 inches of rain in an hour. At least one Alvin home was hit by lightning, causing minor damage.
While flooding in the Alvin and Manvel area was limited with the Tuesday storm, nearby locations in Rosharon and Sugar Land received much more damage.
With the area heavily saturated after the Tuesday storm, a second line of heavy thunderstorms moved into the region Thursday night and into Friday morning. With more than 3 inches of rain dropped in two hours and another inch before morning, flooding became the biggest concern in the region.
With the Alvin police and TxDOT closing several roads due to flooding, Alvin ISD canceled all classes at around 5 a.m. Close to 30 minutes later, Santa Fe ISD also canceled school for the day.
Alvin ISD Superintendent Daniel Combs said the decision was made with the safety of students and district employees in mind.
“Alvin ISD officials have remained in contact with authorities and have been monitoring the roadways throughout the evening,” Combs wrote in a letter to parents. “The decision to cancel school is in large part due to the current condition of roadways in low-lying areas of our district and intermittent power outages at our campuses. The safety of our students and staff remains our number one priority.”
Alvin Community College also closed its campus and halted all classes Friday.
Around Alvin, police blocked off House Street near the Alvin Volunteer Fire Department, Kost Street near Alvin Junior High and Jane Street at Old Galveston Road. Highway 6 at the railroad underpass was also blocked by Alvin police and TxDOT after water rose more than 3 inches over the roadway.
By 8 a.m. Friday morning, the roadways had cleared and were re-opened to traffic.
While Friday night was dry in the region, a third round of storms Saturday brought more localized flooding to the region. Alvin police again had to block roadways, including one area on the Highway 35 Bypass.
By Saturday night, most of the storms had passed, allowing the water to go down.
In Rosharon, local officials were keeping a close eye on the Brazos River as the river reached flood stage and continued to climb.
Even Congressman Pete Olson was watching the river closely as it approached 50 feet with more rain coming. While the river crested well above flood stage, it fell short of the record of just over 52 feet.
According to the National Weather Service, more rain is in the forecast in the coming days, but the forecasts do not call for the intense storms that hit the Alvin area last week.
