Scattered thunderstorms associated with the approach of an offshore low pressure system produced several tornadoes on the evening of January 8 and the early morning of January 9. These tornadoes resulted in several instances of property and tree damage across the Greater Houston Area. Some non-tornadic storms also produced strong, damaging wind gusts. Later, heavy rainfall associated with continuing thunderstorm activity resulted in flash flooding across the Houston Metro.

This EF1 tornado tracked from a wooded area, through North Hollow Estates then across the City of Humble with damage to trees and a couple of structures. Vans were flipped in a church parking lot. One retail building was destroyed with the loss of its roof and three walls. The post office also sustained minor damage.

This EF1 tornado snapped the trunks or uprooted several large trees with a few of them on structures. The most significant damage was along Palmetto Lane and Hamblen Road near its intersection with Red Bud Lane.

9 minutes of warning. NWS HGX issued a tornado warning for this county at 07:16 UTC, 9 minutes before the tornado touched down, in force until 07:44 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 05:40 UTC.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
