After 12-Day Rampage, Hurricane Matthew Leaves More Than 1,000 Dead
By Jeff Masters and Bob Henson
After a devastating 12-day rampage from the Caribbean to the U.S. Mid-Atlantic, Hurricane Matthew was reclassified as a post-tropical cyclone at 5 a.m. EDT Sunday by the National Hurricane Center (NHC). Matthew wasn't exactly slacking off—its top sustained winds remained 75 mph as of NHC's 2 p.m. Sunday advisory—but it no longer had the warm core required for tropical-cyclone status. At 2 p.m. EDT, Matthew was located about 150 miles east of Cape Hatteras, North Carolina, moving east at 15 mph. After days of computer models suggesting a potential loop back toward Florida, it now appears Matthew will continue eastward and gradually dissipate.

It will be some time before we have a more complete sense of Matthew's toll, but we already know that it is the deadliest hurricane in the Western Hemisphere since 2005. In Haiti, Matthew took at least 1,000 lives and left entire towns across southern Haiti almost completely destroyed. A handful of deaths and significant damage were also reported in Cuba, Jamaica, The Bahamas, Colombia, Saint Vincent and the Grenadines, and the Dominican Republic. After Haiti, it was the U.S. that took the worst of Matthew's wrath. At least 17 U.S. deaths have been reported and insured damage is expected to total at least $4 billion. See our Saturday post for details on how you can provide much-needed help to those struggling with the aftermath of Matthew.
From Florida to Virginia, Astounding Rains and Storm Surge
Matthew traced a path remarkably similar to the coastline of the Southeast U.S. Although its center stayed within about 50 miles of the coast for more than 36 hours and hundreds of miles, Matthew officially came ashore only briefly as a Category 1 hurricane along the South Carolina and North Carolina coast on Saturday afternoon. Matthew's overall path kept its strongest winds just offshore, with few or no reports of sustained hurricane-force winds along the Southeast U.S. coast. Top wind gusts compiled by weather.com included 107 mph at Cape Canaveral, Florida (collected on a tower 54 feet above ground level) and 96 mph at Tybee Island, Georgia.
Matthew's just-offshore track may have spared the Southeast from billions of dollars in wind damage, but it didn't keep the hurricane from packing a phenomenal punch in the form of water. Like several other U.S. hurricanes in the last decade, including Ike (2008) and Sandy (2012), Matthew delivered a much more severe storm surge than one might expect from its landfall strength, thanks to the water built up by much higher winds earlier in its life offshore. Matthew's track along the concave Southeast coast also enhanced its ability to produce high surge. Major storm surge was reported as far north as the Hampton Roads area of southeast Virginia, which received an unexpectedly powerful blow from Matthew that also included tropical-storm-strength sustained winds (including a peak gust of 75 mph at Oceana Naval Air Station in Virginia Beach) and torrential rain.
As of 8 a.m. EDT Sunday, Oct. 9, here are the approximate peak storm surges observed over the preceding 48 hours at all the tide gauges with a long-term period of record (at least a few decades) along the coasts of northern Florida, Georgia, South Carolina, North Carolina and Virginia. (Storm surge is the added water produced by a storm atop the normal tidal cycles).

Torrential Rains Wallop Unexpectedly Large Parts of the Carolinas and Virginia
Forecasters knew for days that extremely heavy rain was likely to develop on the north side of Matthew as it moved up the Southeast coast. As hurricanes move into the midlatitudes, they often interact with pre-existing frontal systems that intensify the rain-making processes on the poleward side of the storm. Matthew ended up generating torrential rain near the Southeast coast, as predicted, but it also produced record-smashing rainfall well inland and considerably further north than expected, especially over North Carolina and southeast Virginia. More than 880 rescues had taken place across North Carolina as of Sunday morning, according to Gov. Pat McCrory.
Here are the highest storm totals observed in each state along Matthew's path as of 11 a.m. EDT Sunday:
- Florida: 7.89", Sanford/Orlando
- Georgia: 17.49", Savannah/Hunter Army Air Field
- South Carolina: 14.04", Beaufort MCAS
- North Carolina: 15.65", William O. Huske Locke 3
- Virginia: 12.84", 10 miles northwest of Chesapeake
- Maryland: 5.52", 6 miles south of Berlin
- Delaware: 3.13", Seaford
From Friday into Saturday, Savannah International Airport broke the city's official 24-hour rainfall record of 11.44" on Sept. 17-18, 1928, according to Weather Underground weather historian Christopher Burt. It's quite possible that an even higher 24-hour reading will be confirmed from one of the other Savannah-area reporting stations, as suggested by the storm total above.
Norfolk, Virginia, received 7.44" of rain on Saturday, making it the city's wettest October day on record (beating 6.23" from Oct. 17, 1999). Little more than three months ago, Norfolk set its all-time July calendar-day rainfall record with 6.98" on the 31st.
Raleigh-Durham International Airport picked up 6.45" on Saturday, beating the area's previous all-time calendar-day rainfall record of 5.96" set on Oct. 1, 1929. Raleigh-area records extend back to 1887.
Perhaps the single most phenomenal record on Saturday was at Fayetteville, North Carolina, where 14.00" of rain was reported on Saturday. This demolished the city's previous all-time calendar-day record of 6.80" observed during Hurricane Floyd on Sept. 16, 1999. In fact, there are only four entire months in Fayetteville weather history that have received more rain than Fayetteville picked up in 24 hours on Saturday! Fayetteville records extend back to 1871. The flooding situation in the Fayetteville area was made even worse by very heavy rains observed in parts of the area during late September.
Record Atmospheric Moisture Contributed to Matthew's Deluge
Several locations along Matthew's path through the Southeast recorded incredibly high amounts of atmospheric moisture on Friday and Saturday. At least two sites had record amounts of precipitable water (the total amount of liquid water that would cover the ground over a given location if all the moisture in a column of air above was condensed). These readings are taken with radiosonde soundings (balloon-borne instrument packages) that have been conducted regularly since 1948.
Jacksonville, Florida: 2.85" at 8 p.m. EDT Friday
Previous record: 2.82" on July 20, 1983.
Charleston, South Carolina: 2.93" at 2 a.m. EDT Saturday (special sounding)
Previous record: 2.70" on Aug. 15, 2010.
2nd place: Newport/Cape Hatteras, North Carolina: 2.85" at 8 p.m. EDT Saturday
Record: 3.05" on Aug. 27, 2011.
Matthew's Place in Hurricane Annals
Dr. Phil Klotzbach (Colorado State University) has assembled a handy list of the many records set during Matthew's long life. Here are a few highlights:
Intensity: Matthew was the lowest-latitude Category 5 hurricane on record in the Atlantic. Its strengthening of 80 mph in just 24 hours was the third fastest on record for the Atlantic, behind only Wilma (2005) and Felix (2007).
Longevity: Matthew maintained Category 4 or 5 strength for 102 hours, the longest such stretch on record for October in the Atlantic. Its 7.25 days as a major storm (Category 3 or stronger) is the fifth longest such period for any hurricane since satellite observations began in the Atlantic in 1966.
Landfall: Matthew is the first storm on record to make landfall as a major hurricane in Haiti, Cuba and the Bahamas. Since 1866, the only two hurricanes to strike the Bahamas at Category 4 strength in October are Matthew and last year's Joaquin. Matthew's landfall near Myrtle Beach made it the first hurricane to strike the U.S. Atlantic coast north of Georgia in October since Hazel (1954).

A New Lease on Life for Nicole
Tropical Storm Nicole continues to languish in the open Atlantic. As of 11 a.m. EDT Sunday, Nicole was nearly stationary, spinning about 575 miles south of Bermuda with top sustained winds of around 60 mph. As a blocking ridge to its north moves eastward, Nicole should begin moving north an at increasing rate over the next couple of days. By midweek, it will be over the record-warm waters of the subtropical North Atlantic, which helped boost Hurricane Gaston to Category 3 strength at latitude 30°N in late August. With wind shear over Nicole decreasing by midweek, the storm may a chance to regain much of the strength it had on Friday. The 12Z Sunday run of the HWRF, one of our best intensity models, brings Nicole back to Category 2 strength by late this week. Our best track models (the GFS, ECMWF and UKMET) differ on whether Nicole will pass to the west or the east of Bermuda around Thursday. Given this uncertainty, as well as Nicole's potential to intensify, Bermudians should monitor this storm closely.

Though the science has shown sugary drinks are not healthy for children, fruit drinks and similar beverages accounted for more than half of all children's drink sales in 2018, according to a new report.
Farms with just one or a handful of different crops encourage fewer species of pollinating and pest-controlling insects to linger, ultimately winnowing away crop yields, according to a new study.
Up to half of the detrimental impacts of the "landscape simplification" that monocropping entails come as a result of a diminished mix of ecosystem service-providing insects, a team of scientists reported Oct. 16 in the journal Science Advances.

"Our study shows that biodiversity is essential to ensure the provision of ecosystem services and to maintain a high and stable agricultural production," Matteo Dainese, the study's lead author and a biologist at Eurac Research in Bolzano, Italy, said in a statement.
It stands to reason that, with declines in the sheer numbers of insects that ferry pollen from plant to plant and keep crop-eating pests under control, these services will wane as well. But until now, it hasn't been clear how monocultures affect the number and mix of these species or how crop yields might change as a result.
Aiming to solve these questions, Dainese and his colleagues pulled together data from 89 studies cutting across a variety of landscapes, from the tropics of Asia and Africa to the higher latitudes of northern Europe. They tabulated the number of pollinating and pest-controlling insects at these sites — both the absolute number of individuals and the number of species — along with an assessment of the ecosystem services the insects provided.
In almost all of the studies they looked at, the team found that a more diverse pool of these species translated into more pollination and greater pest control. They also showed that simplified landscapes supported fewer species of service-providing insects, which ultimately led to lower crop yields.
The researchers also looked at a third measure of the makeup of insect populations — what they called "evenness." In natural ecosystems, a handful of dominant species with many more individuals typically live alongside a higher number of rarer species. The team found as landscapes became less diverse, dominant species numbers dwindled and rare species gained ground. This resulting, more equitable mix led to less pollination (though it didn't end up affecting pest control).
"Our study provides strong empirical support for the potential benefits of new pathways to sustainable agriculture that aim to reconcile the protection of biodiversity and the production of food for increasing human populations," Ingolf Steffan-Dewenter, one of the study's authors and an animal ecologist at the University of Würzburg in Germany, said in the statement.
The scientists figure that the richness of pollinator species explains around a third of the harmful impacts of less diverse landscapes, while the richness of pest-controlling species accounts for about half of the same measure. In their view, the results of their research point to the need to protect biodiversity on and around crops in an uncertain future.
"Under future conditions with ongoing global change and more frequent extreme climate events, the value of farmland biodiversity ensuring resilience against environmental disturbances will become even more important," Steffan-Dewenter said.

Greenland had quite the summer. It rose from peaceful obscurity to global headliner as ice melted so swiftly and massively that many were left grasping for adjectives. Then, Greenland's profile was further boosted, albeit not to its delight, when President Trump expressed interest in buying it, only to be summarily dismissed by the Danish prime minister.
During that time I happened to be in East Greenland, both as an observer of the stark effects of climate change and as a witness to local dialogue about presidential real estate aspirations, polar bear migrations and Greenland's sudden emergence as a trending topic.
