Hohonu

Flooding?is?not?just?about climate change; it’s about how we adapt as communities and safeguard the rhythms of our daily lives. These events disrupt more than property—they disrupt our schools, businesses, and the ways we connect with each other. The real challenge lies in building resilience,?not?only in infrastructure but in our collective capacity to anticipate, respond, and recover. By focusing on solutions rooted in collaboration and local action, we can ensure that our communities remain strong and adaptable in the face of a changing world.

Had a blast and learned lots at the NOAA 2024 Coastal Inundation Community of Practice Workshop in Seattle. On Tuesday, I shared that we were predicting a 98% chance for ~1-2 feet of flooding at our Tenean Beach, Boston, site during yesterday's King Tide. How did we do? Not so bad ;-)

?? Product announcement! ?? November will bring #high #tides and possible #flooding across certain regions of the U.S. Be #prepared by signing up for advanced and real-time #king tide text alerting from Hohonu. This king tide text alert feature ?? is now available for hundreds of NOAA and Hohonu stations across the country. By signing up, you’ll be notified a week in advance of a king tide event impacting your area, plus the day that the king tide event begins. Sign up with a few clicks by visiting your nearest location here: https://lnkd.in/gYEtBK6y NOAA: National Oceanic & Atmospheric Administration advises to be on the lookout for high tide flooding in: Boston, MA Sandy Hook, NJ Fort Pulaski, GA Toke Point, WA North Spit, CA Hilo Bay, Kuhio Bay, HI Note: A “king tide” period for these purposes are defined as the dates being within 3 days of a perigean spring tide, and the mean likelihood of stations observing high tide flooding (as projected by NOAA CO-OPS) is greater than 10%

11 Hohonu #tide and #flood sensors were deployed across 600 square miles in Lee County, which allowed for real-time tracking of #storm #surge and flooding during Hurricanes Helene and Milton. These #sensors recorded over 5 feet of storm surge across the area - data that had previously largely relied on sparse data, pictures, or anecdotal evidence. With this real-time data, emergency responders can make better-informed decisions, knowing precisely how much water covered roads and properties. This #data will significantly aid future flood #predictions, particularly in areas like St. James City on Pine Island, Florida. Between Hurricanes Milton and Helene substantial new data was collected, allowing for a clearer understanding of how future storms may impact specific regions based on factors like wind speed, precipitation, and storm surge.

People often ask me about longevity and durability of lower-cost sensor packages that we deploy. During Hurricane Milton, our sensor on the Matlacha Bridge in Lee County, FL not only survived, but also kept telemetering 1-minute average water level data in near-real-time during a direct hit from a tornado. We don't claim they're all tornado or hurricane rated, but we've been at this for a while ;-) and more importantly, the value of having a distributed network of lower cost sensors deployed shines through not only in accessing better spatial variability, but also in redundancy of multiple sensor types.

How often is a #critical access road flooded? For how long? And how does this impact #response from the local fire department in the case of #emergency? In partnership with Woods Hole Group, Inc. and the Yarmouth Fire Department, Hohonu has been helping to answer these questions for Great Island Homeowner's Association, a community group located in Yarmouth, #Massachusetts. It was believed that the Great Island road flooded a few times per year, but Hohonu revealed it flooded 50 times during the first 6-months of installing a #flood #sensor. Often, flooding occurred at night when no one was around to witness it. Watch our latest case study video to learn more about how Hohonu is helping communities like Great Island prepare for emergencies and for the #future.

Hohonu has a flood sensor located near the pictured Chart House on Long Wharf Pier in Boston. The real-time data can be viewed for free, without creating an account: https://lnkd.in/gsb8_BJT

The Climate Resilience Network unifies the expertise of University of Maryland – College of Computer, Mathematical, and Natural Sciences and College of Behavioral and Social Sciences, University of Maryland scientists with the immediate requirements of Maryland’s decision-makers to address the complexities of climate change. Working alongside stakeholders, researchers from this Grand Challenges Institutional Grant can assess regional needs and find innovative solutions rooted in both the real demands of the community as well as University of Maryland's groundbreaking research. For example, the Climate Resilience Network recently worked Annapolis local leaders to introduce HydroNet, a new water-level monitoring project designed to prepare coastal communities like Annapolis for the increasing impacts of flooding due to climate change. Take a look at what Ralph Ferraro, Tim Canty, James Farquhar, Tatiana Loboda, Sumant Nigam, Karen Prestegaard, Sujay Kaushal, Mong-Han Huang, Russell Dickerson, Kara Mobley, Mike Humber, and James Hyde are doing to mitigate climate change: https://lnkd.in/g87bXKtw

We are wishing for safety for all of those impacted by #Hurricanes #Helene and #Milton. A month ago, Lee County Emergency Management began deploying Hohonu sensors throughout the county in anticipation of a hurricane event. Hurricane Helene, and now Milton, have since then devastated the Florida coastline. Hohonu sensors deployed at sites like New Pass Bridge recorded extreme #storm #surge in both events, and others like Matlacha Bridge yesterday survived a direct hit from a #tornado. Not all of our sensors survived, but many have. We hope this data can be used to better inform decisions in real-time, as well as for future events. Disclaimer: The image shown references data in the NAVD88 datum. This data will soon be converted to MHHW, the datum typically used for flooding events, as soon as each respective monitoring location has been installed for at least 35 days.

Hohonu deployed #tidal, #water-level sensors around Lee County, FL to manage storm surge data and flood predictions. Hohonu's sensor data will be tracking inundation through the #Hurricane #Milton event. Check out the Tidecast for iOS data for yourself at dashboard.hohonu.io.
