NWS: Excessive Heat Warning
July 12, 2024 updated 744 pm PDT
Excessive Heat Warning URGENT weather message issued 246 am July 12 from National Weather Service Hanford, NY
EXCESSIVE HEAT WARNING NOW IN EFFECT UNTIL 10 AM PDT SUNDAY...Dangerously hot conditions as extreme Heat-Risk will occur through the duration of this heat wave through a portion of central California.
This level of rare, long-duration extreme heat with little to no overnight relief affects everyone, especially those without effective cooling and/or adequate hydration.
Impacts likely in most health systems, heat-sensitive industries and infrastructure. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.
Do not leave young children and pets unattended in vehicles. Car interiors will reach lethal temperatures in a matter of minutes.
Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning
or evening. Take action when you see symptoms of heat exhaustion and heat stroke. To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat
should be moved to a cool and shaded location. Heat stroke is an
emergency! Call 9 1 1.
Streamflow Situation from the network of monitors of USGS California Water Science Center
Streamflows run at seasonal normal through north and central California Friday, heading up to much above normal ratings in the south. The highest flow values registering on the USGS network today are 98th percentile in Regions 2 Half Moon Bay area, and 97th percentile on Santa Inez River near Lompoc in coastal Region 3. Extreme high flow is recorded 99th percentile Big Rock Creek near Valyermo. Extreme low flow is found on Mohave River in Region 6. Moderate drought rating is applied to southeast Siskiyou County, northeast Shasta County, west Lassan County.
HAB Tracker from state sources and tje federal satellite monitoring program of the NOAA National Centers for Coastal Ocean Science
California
Danger HAB postings for Region 2 include Lake Temescal and Lago Los Osos in Alameda County, Lake Anza in Contra Costa County; for Region 5 certain locations in Clear Lake in Lake County; Region 8 Lake Elsinore in Riverside County.
Warning HAB signage has gone up for sites in Region 5 including Forbes Creek and sites on Clear Lake in Lake County; Region 2 Lake Merced in San Franscisco County, Horseshoe Lake and Shinn Pond in Alameda County
The Freshwater Harmful Algal Bloom (FHAB) Reports Map is maintained by the State Water Resources Control Board (CA Water Boards) from voluntary reporting of suspicious algae, with subsequent verification or eliminaton of the report by authorities. The CA Water Boards coordinate with state and local agencies for follow-up field work sampling and water testing leading to recreational advisories being posted. Signage notifying of HABs in California are as follows:
- Caution Harmful Algae may be present
- Warning Toxins from algae in this water can harm people and kill animals
- Danger Toxins from algae in this water can harm people and kill animals
- Check for Algae toxic algal mats may be present in this water
- Toxic Algae Alert toxic algal mats ARE present in this water
The CA Water Boards guidance for HABs involves the above signage for public awareness. Further, "Practicing Healthy Water Habits" around all water bodies is encouraged, whether these water bodies are posted with signage or not. Always avoid contact with water bearing algae blooms. For questions, please contact the HAB Hotline by email to CyanoHAB.Reports@waterboards.ca.gov or phone 1-800-222-1222.
Please refer to the Cal HAB Monitoring and Alert Program here for information on marine HABs.
New York
The lastest image with a clear view of the Baie Missisquoi HAB was snapped Monday July 8, showing the high concentration bloom stretching from north shore in Canada to the shore of Missisquoi National Wildlife Refuge on the US side of the border. This HAB appears to match the color scale for a concentration around 900 thousand cells per 100 ml standard sample in the south end, reaching an extreme high concentration 2 million cells per 100 ml along the north shore in Canada. The latest image uploaded by the NCCOS for Lake Champlain was captured Thursday July 11, completely cloud obscured. From the NYS HABs reporting center, ninety-one active blooms are confirmed Friday afternoon including first HABs of the season confirmed for Seneca River, Oakland Lake and Golden Pond. New and additional HAB reports have been confirmed for Beaver Dam Lake, Ellicott Creek and Lake Welch. The latest list of HABs by water body and location descriptions is found here.
Louisiana: A massive HAB bloom has emerged in Lake Pontchartrain overnight, five by five nautical miles open water bloom in the east half of the lake showing between clouds. Dispersed HABs show through the west half of the lake Concentration matches the color scale for a moderate bloom, around 100 thousand cells per 100 ml. This is the first sign of widespread HABs in Lake Pontchartrain this season. The high concentration lakewide HAB we have been observing in Lake Verret appears in the latest image around 600 to 700 cells per 100 ml, the remaining area is cloud obscured. Southeast LA water bodies at are captured in a wide angle pass by the Copernicus-Sentinel III satellite, catching Lake Pontchartrain to Black Bay in frame. The latest image was captured July 11 at a surface wind speed 6.1 mph. Updates to the map and HAB report are in progress, more to follow. The latest HAB report for Louisiana is available here.
Ohio: Lake Erie west basin is captured by the NCCOS monitoring satellite, the latest upload a stunning clear image of the Lake Erie bloom in full color captured July 11 at surface wind speed 10 mph. The Lake Erie HAB now extends more than 20 nm from Toledo, up past Monroe Detroit Beach Woodland Beach to Stony Point. One large appendage off the main bloom stem extends in a five-mile wide band beginning from center of the Michigan shore reaching fifteen nautical miles into open water. At the Ohio shoreline, the HAB snakes along Maumee Bay State Park, Niles Beach, up around Cedar Point National Wildlife Refuge and wraps Reno Beach up to the Magee Marsh and Metzger Marsh Wildlife areas. Sandusky Bay bloom Aphanizomenon remains parked in the bay, concentration around 800 thousand cells per 100 ml. Updates to the map and report are in progress. The latest Ohio HAB report is available here.
See the North American drainage basin map here, scroll all the way down to see how surface water moves across the continent into the Pacific, Atlantic, Gulf of Mexico and Arctic Oceans. WT Media Group tells the story of water in three countries, Canada, USA and Mexico. See the drinking water advisories, hazardous spills, floods, drought and harmful algal blooms plotted on the maps, as the water flows. Check out the CrimeBox for historic prosecutions under the Clean Water Act, the Safe Drinking Water Act box for details on public drinking water facilities, interviews with the scientists and tech developers on the leading edge of clean water technology here.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
Harmful Algal Blooms: WT follows the movement and growth of harmful algal blooms (HABs) as provided by the satellite monitoring program of the NCCOS for New York's Lake Champlain, Ohio's Lake Erie and Louisiana's Lake Pontchartrain and surrounding area. Interpretation of satellite images is best in clear conditions at wind speed less than 4 mph, where the appearance and extent of HABs is reliably matched to a color scale for concentration. HABs are known to produce algal toxins of concern for raw drinking water sources and recreational water bodies. Plan beach access to avoid HABs and consider carrying a rapid test kit to detect the toxin microcystins.
