India – As a result of heavy rainfall in Himachal Pradesh on Sunday night, the state witnessed flash floods on Monday. Two persons are reportedly missing in Kangra district. In Kangra district, houses were flooded and vehicles were seen floating in the water. Bhagsu Nag in Dharamshala experienced flooding and Manjhi river’s water level rose. In Rakkar village, the road turned into a drain. A similar situation was observed across Kangra district.

High Tide Floods to get worse

High-tide floods, also called “nuisance floods,” occur in coastal areas when tides reach about 2 feet (0.6 meters) above the daily average high tide and begin to flood onto streets or seep through storm drains. True to their nickname, these floods are more of a nuisance than an outright calamity, inundating streets and homes, forcing businesses to close and causing cesspools to overflow — but the longer they last, the more damage they can do.

The U.S. experienced more than 600 of these floods in 2019, according to the National Oceanic and Atmospheric Administration (NOAA). But now, a new study led by NASA warns that nuisance floods will become a much more frequent occurrence in the U.S. as soon as the 2030s, with a majority of the U.S. coastline expected to see three to four times as many high-tide flood days each year for at least a decade.

The moon influences the tides, but the power of the moon’s pull isn’t equal from year to year; the moon actually has a “wobble” in its orbit, slightly altering its position relative to Earth on a rhythmic 18.6-year cycle. For half of the cycle, the moon suppresses tides on Earth, resulting in lower high tides and higher low tides. For the other half of the cycle, tides are amplified, with higher high tides and lower low tides, according to NASA.

We are currently in the tide-amplifying part of the cycle; the next tide-amplifying cycle begins in the mid-2030s; — and, by then, global sea levels will have risen enough to make those higher-than-normal high tides particularly troublesome
