- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Llano County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

National Weather Service narrative
Heavy rain across Llano County and points west produced a large flash flood on the Llano River. The flash flood emptied into Lake LBJ at Kingland, causing water to back up in the lake and flood areas as early as 7 am north of Kingland. Many homes along the canals had 4-6 feet of water in them. Many homes along Lake LBJ in Kingsland flooded, as well as areas down the lake at Sunrise Beach and Horseshoe Bay. Lake LBJ started to rise in the predawn hours and continued high through the day. In Llano County, preliminary damage assessments show estimates of 38 homes destroyed, 494 with Major damage, 140 with minor damage, and 49 that were affected. A few businesses also took on water.…

National Weather Service narrative
Heavy rain overnight produced flash flooding that washed away the FM 2900 bridge across the Llano River in Kingsland. A body was recovered near Kingsland and it was determined that this fatality came from a flood in the city of Junction the previous week. Damage to the bridge is estimated at 20 million dollars.
- Jun 22, 1997Flash Flood$5.0 million
National Weather Service narrative
The heavy rain Friday night into Saturday afternoon had left South Central Texas soils saturated. The situation worsened Saturday evening into Sunday as heavy rain associated with the upper low pressure system redeveloped over the western Texas Hill Country. Very heavy rains over the Texas Hill Country Saturday night and Sunday morning caused widespread flooding as well as flash flooding across numerous counties. The heavy rains moved into San Antonio Sunday morning and into the Austin area later in the morning. By Sunday afternoon and evening, areas of showers and thunderstorms had diminished over South Central Texas as the upper low moved into North Texas. Late Sunday evening,…
- Feb 20, 1997Flood, Llano$2.0 million
National Weather Service narrative
Rainfall of up to 8 inches just west of Llano County early in the morning of February 20th produced a very rapid rise and severe flooding along the Llano River. The combination of thunderstorm winds estimated at 40 mph and the wave action on the lake swamped a 16-foot flat bottom boat with two fishermen on Lake Buchanan near 330 pm on the 20th. The two were attempting to move toward shore as the rain became heavier. The Llano crested at 28.8 feet, 178,000 cfs, just under the crest of the severe flood the previous October. This flooding caused major damage to marine and lakeside facilities in Lake LBJ and downstream. Some marine owners received several hundred thousand dollars of…

National Weather Service narrative
A winter storm developed early in the morning of Feb. 1 and continued until well into the afternoon. Rain began falling just before midnight on Wednesday, January 31st, and changed to sleet across the Texas Hill Country just before 2 am CST. as the event spread eastward into the Austin and San Antonio metropolitan areas, the sleet formed sheets of ice over bridges and roadways. In addition, snow began to fall over the Hill Country and Austin areas near noon on the 1st. This event was described as one of the worst in the past ten years by the Austin Office of Emergency Management. Nearly 1000 vehicle accidents were reported in Austin with nearly 700 in San Antonio. Students were…

National Weather Service narrative
The line of thunderstorms struck Kingsland in the late afternoon, producing widespread wind damage across the northwest part of the town. The winds were estimated at 70 knots, based on the worst damage which occurred generally along FM1431 from near its intersection with FM2900 northwestward to Oklahoma Street. This is an area almost one mile long and one half mile wide. Medium to large tree limbs were scattered all over the area and numerous large trees had been knocked over or broken off above the ground. The total number of damaged trees was in the hundreds. In addition, many homes were damaged as the trees fell. Many of these trees had very shallow root systems and some showed…
