On July 26, 9 inches of rain fell in 24 hours in St. Louis, shattering an all-time record, with over a foot of rain measured in some suburbs.
Two days later, dozens died in eastern Kentucky when more than 10 inches of rain fell, sending rivers rising several feet in hours to well beyond historical record crests and washing away homes near the shores.
As August began, another heavy rain event drenched southeastern Illinois with radar estimates of 10-13 inches of rain in just hours.
That same week, the normally arid Death Valley had a year’s worth of rainfall in three hours, swamping the region with floodwaters that shut down every road inside the national park, some suffering moderate to severe damage.
Prepare now! You will never go without electricity with this portable power station!
Just this week, the Dallas-Fort Worth Metroplex suffered widespread flooding as 3 inches of rain fell in an hour, part of a series of thunderstorms that would drop more than 9 inches at the Dallas-Fort Worth International Airport in 24 hours, with some suburbs in eastern Dallas reporting more than 15 inches of rain.
Not to be outdone, some areas of Mississippi saw more than 8 inches of rain in only three hours on Wednesday morning. The sudden flooding caused the need for dozens of rescues and prompted Flash Flood Emergencies.
All six extreme events reached the local threshold to be classified by the National Weather Service as a “1-in-1,000-year” rainfall event, yet all occurred within the same month, much less a millennium.
Last year, deadly flooding that struck New York City and New Jersey from the remnants of Hurricane Ida and catastrophic flooding in west-central Tennessee also qualified as extremely rare 1-in-1,000-year rainfall events.
What ‘1-in-1,000-year’ means?
The term “1-in-1,000-year” rainfall event or flood event may sound like something that is only forecast to occur once every thousand years and that once you experience such an event, you’d expect to be in the clear until the year 3022.
That’s not quite how it works. Instead, that term is given to an event that forecasters deem only to have a 0.1% chance of occurring in any given year – a 1 in 1,000 chance. An 0.5% chance is deemed a “1-in-500-year” event, while a 1% chance is a “1-in-100-year” event, and so forth.
The National Oceanic and Atmospheric Administration’s Office of Water Prediction oversees researching historical rainfall events across the nation to classify how much rain needs to fall within certain periods (such as an hour, several hours, or days) relative to their climate averages to reach each probability threshold. For example, it took far less rain in Death Valley (just under 1.5 inches) than St. Louis (over 9 inches) to reach the 0.1% probability threshold.
With so many of what are supposed to be exceedingly rare events occurring with much more frequency, you might be wondering if the calculations are off.
Why are downpours so bad now?
Warmer ocean temperatures allow increased evaporation and an increase in available water vapor. Meanwhile, warmer air can hold more water vapor. As Earth’s temperatures rise, storms will have access to even more moisture when heavy rainfall events occur.
According to the U.S. Environmental Protection Agency, nine of the top 10 years for extreme one-day precipitation between 1910 and 2020 have occurred since 1996. The EPA added, “the prevalence of extreme single-day precipitation events remained fairly steady between 1910 and the 1980s, but has risen substantially since then.”
The Office of Water Prediction’s Hydrometeorological Design Studies Center was already in a yearslong process of researching and updating the precipitation frequency thresholds across the nation and has created interactive maps to allow users to calculate the estimated frequency of certain rainfall amounts in regions where the research is complete.
However, those maps will likely get a fresh update in the years ahead.

The recently enacted infrastructure law includes funding allowing NOAA to further analyze any changes and trends in observed rainfall events and incorporate them into a national update of precipitation frequency estimates. That research is already underway.
Not 1-in-1,000-year flood events
With these extreme and rare rainfall and flooding events making headlines, NOAA stressed that 1-in-1,000-year rain events are not the same as 1-in-1,000-year flood events.
An extreme rainfall event that hits that criteria may not lead to a 1,000-year flood event, just as a 1,000-year flood event may not have been triggered by a 1,000-year rain event. Thus, the terms should not be used interchangeably, according to NOAA.
Stock up on Iodine tablets for the next nuclear disaster…
NOAA is in charge of determining extreme rainfall probabilities, while the United States Geological Survey is in charge of determining such probabilities when it comes to flooding.
I find it weird that everybody blames climate change and/or global warming, and always forget to speak about geoengineering and weather manipulation as the major sources of the weather and climate chaos we are currently facing and experiencing… Stop playing the weather wizard! [WSFA, Fox News]

Hmmm. Had it right: ZetaTalk Prediction 7/15/1995: Weather changes heralding the giant comet’s approach will at first be within normal parameters. As long as meteorologists can find a similar pattern on the books or an old timer can be found to regale us with tales of the old days, no one will get unduly alarmed. The weather, after all, is a constant source of conversation, but the intensity of these discussions will change when the effects on food chains relied upon by man move outside of familiar boundaries. It is at this point that Alarm Bells will go off. All attempts to explain the changes based on Global Warming from the Greenhouse effect will run into snags as the weather will refuse to be predictable. Areas of the world which have been deserts throughout mankind’s memory will become swamps under constant and repeated rains. Temperate climates used to periodic gentle rainfall will suffer intractable droughts. Then this will switch about, for no apparent reason.
Man does not control the weather. They lie about everything including their ability to control the weather. A little logical thinking will reveal how absurd the idea is. The biggest one is NOBODY benifits from it. Man connot generate enough power to control weather on a worldwide scale even if they had the technology. But the lies make them appear more powerful and prevent people from seeing what’s really going on. This method of controlling the people of the world has worked for thousands of years.
Many people are not aware of the MeltWaterPulse 1B: it happened about 12,500 years ago. Prior to that sea levels were constant for a 1000 years. Then suddenly sea levels rose by 26.7 feet in 100 years then continued to rise up to 1.5 inches every year for the next 4000 years. At the same time Greenland’s ice pack grew! In June of 22 the ISS video recorded a large number of large ice clouds flying in from space to hit earth, leftovers from the interplanetary storm MeltWaterPulse 1B. However, this FACT!!!! does not fit what you are expected to believe.
God is pissed.
NO man can do this.
Give glory to the Lord. Even if its negative.
The weather has been weaponized. They will cause extreme drought and fire in the southwest and they will flood out other areas of the nation. They own and control the weather completely now. Global climate change is cover for geoengineering and weather weaponry.
China retaliation with the weather, due to all the other weather manipulation that the U.S did last year?
More flooding is expeced with Quakes in USA , California to Alaska 6 Plus till Sep 15 2022 …
HAARP is active for world, Pakistan recently also went under water… World is flooded is this act of God to people of all over or is manifactured ?
Weather is most definately being weaponised (was used to entirely flood the Ho Chi Ming Trail during Viet Nam war to help prevent the N Vietnamese from getting artillary/munitions to S Vietnam on that Trail. God uses both good and bad people/ situations to get His will accomplished. We are now in the End Times and things worldwide are steadily getting worse, have you noticed? Time is short, receive Jesus as your Lord and Savior while you still can. See Matthew 24: All Prophesies so far have come with true @100%! ! accuracy and Will continue to do so until Jesus returns. Let no one deceive you regarding this Fact. Matthew 24: Perfectly describes the world’s condition today. We live in a spiritual world where both evil and good co-exist. Check it out. God Bless you all.
Hum I guess they think we have short memories.
All places described have had rain and flood events that match fairly recent history.Say forty to fifty years.Anyone remember Hurricanes Agnes and Camille.
The drought though is a once in 500 to 1000 year event.Its normal and so is the fallout.
Time to learn water capture from floods.It will help avert and mitigate floods and provide a back up water source.Would we need large underground storage yes.Will it cost much?
Perhaps but look at the recurring costs of floods and drought.Doing something like this makes more sense than constantly rebuilding infrastructure commercial buildings homes.Replacing cars trucks personal belongings.Insurance claims.You get the idea.
The current flood walls could be used not only to prevent floods but direct the waters to underground cisterns perhaps under the same rivers that are flooding.The drought is a perfect time to do this.The bed can be easily dug and the underground cistern placed.The specs would have to be worked out for each rivers depth soil maximum flood plus 20 or more feet to allow for error.

21 straight days with rain in my area. I ain’t complaining. All my trees grew alot. Seeing the best season in seven years. My cherry trees really like rain here. Apple trees love it too.
More light rain in my neck of the woods today. Then sunshine. We get that alot up in the mountains too. It’s good, as it allows my solar to invert power and make up for inclement weather, where clouds prevent power from inverting to solar batteries. Then I don’t have to run my gasoline generator.
Next year, I want to plan a way to catch rain water, and divert it from raingutters to a tank. Rainwater is excellent for germinating seeds. Your percentage goes way up, and seedlings are very healthy too. I wish an apiary were near my land. I would have better yields on fruit trees. Sadly, a late frost ruined my blossoms this year. We had good activity with wild bees, but the frost will take away all that benefit. Sucks. I got four pears, and the bird ate one. So three Bartlett pears, on a season two tree, shielded by a cedar. That’s why the frost didn’t get that tree, which is outside the orchard. 3 is better than nothing.
Earth Wobble increasing. Natural event. Will keep getting more extreme as we approach the Pole Shift. One note: This site is the only one that will post my comments making reference to Nibiru. They allow posting all sorts of strange comments. But a reference to Nibiru gets ignored. Hmmm. I wonder why?
