What happened

The episode as NWS HNX wrote it up.

Large water releases from Pine Flat Dam resulted in flooding along portions of the Kings River between June 18 and June 29. Evacuations began at Riverland RV park near Kingsburg on June 18. A levee breech near the Kings River Country Club near Kingsburg occurred on June 23 followed by a second breech just downstream of the first levee breech on June 24. As a result of the second breech, 90 homes were threatened by flooding in Tulare County. 300 people were evacuated as water ponded up to 12 feet deep around homes and 7 structures were damaged. A sandbagging operation took place on June 24 and June 25 in Tulare County on on June 25 and June 26 using over 1000 sandbags. Releases were cut back at Pine Flat Dam on June 26 and the flooding downstream receded by June 29.

Area forecast discussion, Jun 19, 3:11 PM PST, 1 hour 49 minutes before
Area Forecast Discussion
National Weather Service San Joaquin Valley - Hanford CA
411 PM PDT Mon Jun 19 2017

.SYNOPSIS...A strong ridge of high pressure will maintain very hot
conditions across the area through at least Thursday with near
record temperatures. Isolated afternoon thunderstorms are possible
along the Sierra crest each day.

&&

.DISCUSSION...The heat wave continues as strong high pressure
centered over Arizona dominates the region. Temperatures trends
are generally running up 3-5 degrees from this time yesterday.
High temperatures across the San Joaquin Valley, lower foothills
and Kern County Desert are on track to generally top out from
105-110 degrees with a few of the typically hotter locations
reaching around 112 degrees. As of 3 PM, record highs for the day
have already been tied at Fresno and Bakersfield. So these will
almost certainly be broken later this afternoon. The Excessive
Heat Warning remains in effect through Thursday with little change
in temperatures. Record highs over the next few days are a little
higher, but may still be tied or possibly even broken. A minor
cooling trend is expected beginning Friday as the ridge weakens.
But it will still be very hot with most of the lower elevations
still into the triple digits through the weekend.

This Heat Wave remains a serious concern as prolonged exposure
to these temperatures, especially after a period of unseasonably
cool weather, will increase the risk of heat related illnesses.
Children, the elderly, and people with chronic ailments are the
most susceptible to heat related illness. Heat exhaustion, cramps,
or in extreme cases, heat stroke can result from prolonged
exposure to these conditions. Also, area waterways are running
very cold and fast, increasing the risk for hypothermia, and water
rescues. Pets, crops, and livestock will also require extra care
through the hot weather.

In addition to the heat risks, a stagnant air mass will lead to
worsening air quality in the San Joaquin Valley.

Daytime heating has led to some cumulus development again over
the Sierra, but unlike yesterday, no showers or storms as of yet.
Models indicate enough mid level moisture to maintain a slight
chance around the Sierra crest each day through Thursday.

&&

.AVIATION...
Isolated thunderstorms can be expected over the higher elevations
of the Sierra through 06Z Tuesday. Otherwise, VFR conditions will
prevail across the central California interior during the next 24
hours.

&&

.AIR QUALITY ISSUES...
On Tuesday June 20 2017...Unhealthy for sensitive groups in
Fresno...Kern...Kings and Tulare Counties and Sequoia National
Park and Forest. Further information is available at Valleyair.org

&&

.CERTAINTY...

The level of certainty for days 1 and 2 is high.
The level of certainty for days 3 through 7 is high.

Certainty levels include low...medium...and high. Please visit
