A severe winter storm is expected to hit Michigan with strong winds, blizzards, and large waves, potentially causing power outages and hazardous travel conditions, especially in the Great Lakes region, with emergency crews prepared for restoration efforts.
Hurricane Melissa, a Category 5 storm, has made landfall in Jamaica, causing huge swells and waves, and is moving towards Cuba, Haiti, and the Bahamas, with significant impacts expected.
Satellites have recorded the largest ocean swells ever observed from space, caused by storms like Storm Eddie, which generated waves up to 65 feet that traveled thousands of miles, carrying storm energy across oceans and impacting distant shores, providing new insights into wave dynamics and storm strength.
Hurricane Erin is causing dangerous surf conditions, high waves, and rip currents along the US East Coast, particularly affecting North Carolina and Virginia, with warnings of potential flooding and road closures, although it has not yet made landfall.
Researchers have for the first time used satellite data to measure long river flow waves, enhancing understanding of river dynamics and related hazards, according to a study in Geophysical Research Letters.
Scientists analyzing data from the Cassini spacecraft have found evidence suggesting that waves on Titan's methane and ethane lakes may be eroding and reshaping the moon's shorelines, similar to processes on Earth. This discovery, published in Science Advances, adds to the ongoing debate about the presence of waves on Titan and could provide insights into the moon's wind patterns.
On June 4th, Uluwatu's Outside Corner in Indonesia experienced near-perfect surfing conditions with 8-10 foot waves due to a south/southwest swell. Despite a slow start due to high tide and morning sickness, the waves cleaned up by 11 a.m., providing excellent surf.
Hawaii is bracing for monster waves reaching up to 45 feet in height as a sizable northwest swell is expected to impact the island chain through Friday, prompting the issuance of High Surf Warnings for various shores. The powerful swell originates from a storm north of Hawaii and is anticipated to cause significant coastal impacts, with preparations urged for potential inundation of beaches, affecting coastal properties and roadways. The National Weather Service has warned of powerful longshore and rip currents, urging caution and distance from the shoreline.
Powerful waves unexpectedly surged across the low-lying island of Roi-Namur in the Marshall Islands, causing significant damage to the U.S. Army Garrison Kwajalein Atoll, forcing evacuations and leaving housing, dining facilities, and the theater moderately to severely damaged. The island, vulnerable to sea-level rise, may take months to recover from the flooding, highlighting the vulnerability of low-lying areas to the effects of climate change.
Physicists at the University of Illinois, Urbana-Champaign have potentially discovered the elusive "demon" wave predicted by physicist David Pines in 1956. Using a technique to track electrons as they bounce off materials, the team observed periodic waves rippling through swarms of electrons in a superconducting metal called strontium ruthenate. These waves, known as "modes," closely match Pines' calculations and demonstrate the existence of the long-sought-after demon. While the exact implications of this discovery are still unknown, it adds a new particle to the understanding of metallic effects and highlights the presence of undiscovered vibrations in materials.
The active El Nino pattern has resulted in massive swells and surf as high as 50 feet in Hawaii, attracting surfers and causing coastal flooding. Forecasters predicted waves between 20-30 feet, but heights likely reached much higher. El Nino tends to produce larger-than-normal surf in the North Pacific, particularly in Hawaii and California. The National Weather Service issued High Surf warnings and advisories, cautioning about strong breaking waves and powerful currents. Unfortunately, a swimmer from California disappeared during the rough surf, and search operations have been suspended. Wave heights are expected to decrease by Tuesday.
Strong winds gusting up to 46 mph combined with high spring tides to create spectacular waves along the eastern shores of England. The higher-than-usual water levels challenged seawalls, leading to flood alerts and spray overtopping barriers. Photographer Owen Humphreys captured stunning images of the stormy seas near Seaham Harbour and Tynemouth pier. While the winds were expected to calm down, the high spring tides were set to continue through the weekend and into early next week.
Researchers have developed an accelerating wave equation that allows for the modeling of waves in time-varying materials and sheds light on major problems in physics. The equation reveals a well-defined direction of time, known as the "arrow of time," and shows that the momentum of a wave is conserved within a material medium due to relativistic effects. The framework has implications for the conservation of energy and momentum, resolves the Abraham-Minkowski controversy, and provides insights into the behavior of waves in exotic materials.
Three South African navy personnel have died and a senior officer is in critical condition after seven crew members of a submarine were swept off its deck by big waves during a "vertical transfer" of supplies. The operation was called off and a rescue effort was launched, resulting in the recovery of all seven submariners, but three were pronounced dead. The incident occurred off the coast of Cape Town, which has been experiencing rough seas due to a "spring tide." An inquiry will be conducted into the failed operation and the resulting deaths.
Waves over 30 feet tall crashed into parts of the South Africa coastline, causing damage to vehicles and buildings. The high surf was generated by a strong storm in the Southern Ocean. This occurred during a time of high tides, exacerbating the damage. The affected area lies in the region known as the "Roaring Forties," characterized by strong winds and storms. At least two deaths and several injuries have been linked to the heavy surf.
