Through Atmospheric pressure, Pascal (unit) and Extreme weather

Hurricane watches and warnings were issued prior to Cindy's landfall, hastening evacuations in coastal areas of Louisiana and Texas, with many refugees seeking safety in local shelters. Although tide and wind damage was minimal, extreme rainfall totaling upwards of 23.50 in (597 mm) resulted in severe flooding in many areas of the Texas coastal plain; 4,000 homes were inundated in Jefferson, Orange, and Newton counties, many of them after a levee ruptured in Port Acres. Dozens of residents were forced to flee in rising flood waters, and many streets and roadways became impassable as a result of Cindy's flooding. Strong winds shattered glass windows, and schools throughout southeastern Texas were closed due to the hurricane. Widespread crop damage was observed, with rice, cotton, and pecan harvests suffering the worst. Overall, damage amounted to $12.5 million (1963 USD), and three deaths were recorded.

Meteorological history

The origins of Cindy can be traced to a low-pressure area which formed within a trough positioned approximately 200 mi (320 km) east-northeast of Brownsville, Texas on 16 September, though inclement weather had been reported in the Gulf of Mexico the previous two days. The disturbance soon strengthened into a tropical storm, developing a well-defined circulation near 1800 UTC. By the afternoon, it had become well-organized enough to prompt the New Orleans Weather Bureau office to initiate advisories on the storm, christening it Cindy. A distinct eye was noted on radar around 2000 UTC, and around then a maritime report issued by the SS Sabine documented winds of hurricane intensity, which was the forecasters' basis for operationally upgrading the storm to a hurricane. While operationally classified as a Category 1 hurricane with maximum sustained winds of 80 mph (130 km/h), a reanalysis of the storm in November 2019 as part of the ongoing Atlantic hurricane reanalysis project determined that Cindy never reached hurricane intensity, instead peaking as a tropical storm with maximum sustained winds of 65 mph (100 km/h).

Despite its favorable environment, Cindy remained disorganized, featuring an asymmetric 20 mi (32 km)-wide eye; little further strengthening occurred over the course of the night. Upon Cindy's landfall at High Island the following morning, its atmospheric pressure was measured at 996 mbar (hPa; 29.41 inHg), and winds reached 75 mph (120 km/h). Soon after moving ashore, Cindy became nearly stationary for 18 hours, maintaining tropical storm status before weakening to a tropical depression at 1200 UTC on 18 September. The remnants of Cindy gradually turned westward-to-southwestward and decreased in strength during 18 and 19 September. As a result of its abnormally slow movement and deterioration, extremely heavy rains were recorded over Texas and Louisiana, especially in the storm's northeastern quadrant. Cindy finally dissipated on 20 September while situated west of Corpus Christi.
