2018 Another Year of Extremes

19 November 2018 By In Blog style

This year has had extreme weather from record low Antarctic temperatures of -95 to -98ºC to a large number of super typhoons, Category 4-5 Hurricanes and late season tropical storms. 

Summer 2018
July and August 2018 were warmer than normal with records broken in the UK, and Europe, and many hot periods occurred in the US, while in the Southern hemisphere it was cold and record low temperatures were set in the Antarctic.  Several sites reported temperatures below -95ºC.  The previous record at Vostok was -89ºC.  NASA observed a -98ºC by satellite and this was confirmed on the ground.  Australia, New Zealand and the Andes had heavy winter snows of over 50, 300, and 450 cm according to the ECMWF global 9 km resolution model’s 10-day forecasts.
The hurricane season was active with over nn named storms in the Atlantic and the Pacific.  Several super typhoons hit the western Pacific and Hawaii.  Hurricane Florence developed in the Atlantic and moved steadily toward the Carolina coast striking on 14 September.  Media sources called this the “storm of a lifetime” several days before making landfall.  Models were consistent in placing the track into the Carolinas with maximum rainfall from 700 to 900 mm predicted on the NC coast by the ECMWF model.  NOAA WPC predicted up to 36 inches with extreme flash flooding and storm surges of up to 12-18 feet.  The models had up to 11 m at sea in the NE quadrant. Over one million coastal residents were under a mandatory evacuation on Monday, 4 days before the predicted Friday landfall.  The storm was also moving slowly and feared to stall along the coast.  Forecasts on 091318 had the storm slowly moving into SC then accelerating across Georgia into the Ohio River Valley by 091518.  As I write this paragraph, the storm is 250 miles southeast of NC and moving NW at 17 mph with maximum sustained winds down to 110 from 150 mph yesterday.  The warm 85ºF water temperatures are keeping it an active, serious, catastrophic storm threat.

Fox News reported:

"Hurricane Florence is poised to affect more than 10 million this week in the southeastern U.S. as it makes landfall in the Carolinas.
Once a powerful Category 4 storm, Florence was downgraded to a slow-moving Category 1 hurricane before it makes landfall along the coast of the Carolinas. However, forecasters warn the storm could bring catastrophic storm surges and cause devastating flooding.

SUPER TYPHOON Mangkhut 13 Sept 2118
Super Typhoon Mangkhut is moving toward the Phillippeans with 150 to 180 kt winds and heavy surge and rains. Centre pressure was 933 mb while Florence had 956 mb and 110-140 kt winds as it approached NC.

MANILA, Philippines –  Typhoon Mangkhut retained its ferocious strength and slightly shifted toward more densely populated coastal provinces on Friday as it barreled closer to the northeastern Philippines, where a massive evacuation was underway.
More than 4 million people are at risk from the storm, which the Hawaii-based Joint Typhoon Warning Center categorizes as a super typhoon with powerful winds and gusts equivalent to a category 5 Atlantic hurricane.

Extremes of Weather and Nature 1 October 2018
Super Typhoon Trami passed Japan with damaging winds and rains as it became a category 2 storm. On September 30, a 7.5 magnitude earth quake hit Indonesia causing a huge total wave and massive destruction.  Over 900 bodies have been found and many more missing by 1 October.   On 2 October the death count reached 1,234 as search and recovery crews reached the shore.
BBC reports:
"People in Palu, Indonesia, are growing increasingly desperate for aid after a quake and tsunami hit the town.
Supplies of water, food and fuel are scarce and with roads damaged it is proving hard to bring more in, or reach the more remote areas.
The BBC's Jonathan Head, who is in the town, saw police firing warning shots and tear gas at crowds trying to take items from a small shop.
At least 844 people are confirmed to have been killed by Friday's disaster."

Wikipedia 2 Oct 2018:
The 2018 California wildfires are a series of wildfires that have burned across the state of California during 2018. A total of 6,721 fires had burned an area of 1,508,556 acres (6,104.91 km2), according to the California Department of Forestry and Fire Protection and the National Interagency Fire Center, as of October 1.[1][2][3] The fires caused over $2.959 billion (2018 USD) in damages, including $1.35 billion in fire suppression costs.[4][5][6][7] Through the end of August 2018, Cal Fire alone spent $432 million on operations.[16] The Mendocino Complex Fire burned more than 459,000 acres (1,860 km2), becoming the largest complex fire in the state's history, with the complex's Ranch Fire surpassing the Thomas Fire to become California's single-largest modern wildfire.[17][18]
On August 4, 2018, a national disaster was declared in Northern California, due to the massive wildfires burning there.[19]

 

Hurricane Michael strengthens to Category 4 storm, considered 'extremely dangerous'
By Stephen Sorace | Fox News

Hurricane Michael was upgraded early Wednesday to “an extremely dangerous” Category 4 storm and could be the most powerful storm to hit the Florida Panhandle in 100 years, forecasters said.
The storm’s sustained winds have increased to about 130 mph, with higher gusts, the National Hurricane Center said. The agency said it is possible the storm could strengthen further before it makes landfall later Wednesday.

"This is going to have structure damaging winds along the coast and hurricane force winds inland," meteorologist Ryan Maue of weathermodels.com told the Associated Press.
The Florida Panhandle could see storm surges of up to 13 feet and flash-flooding from heavy rainfall, the NHC said. The chance of tornadoes will also increase into Wednesday over parts of the Panhandle, the northern Florida Peninsula, and southern Georgia.
The storm, which formed off the coast of northern Honduras, has already killed at least 13 people in Honduras, Nicaragua and El Salvador. Torrential rains triggered flash-flooding and landslides in Central America over the weekend.

Extreme fall weather his western Europe
This past week saw heavy mountain snows, extreme rains and debris flows from Malta to Slovenia in flash floods, and destruction of marinas, boats, and seaside facilities.  A deep trough brought cold air into the Med and N Africa spinning up an upper low that produced a flux of moisture out of Africa into the Alps.  The ECMWF predicted 1-3 m of snow over the 10 day period.  They received that much.

Euro News:

1.  Serious flooding around the Arno River has swamped the Italian cities of Pisa and Florence in Friday. According to officials in Pisa, the river has reached levels unseen over the last 20 years.
As a result, a team of emergency workers are erecting barriers and reinforcing banks to try to channel water into the sea.
2. Venice heavily-flooded as deadly storms batter Italy
Venice was shut off on Monday after heavy rain left much of the city submerged.
Local authorities blocked access to St Mark's Square and said high tide had reached the fourth highest level ever recorded.

Elsewhere in the country the bad weather left at least nine people dead and four others seriously injured, said interior minister Matteo Salvini.

Avoriaz in France earlier this morning:
Heavy snowfall in the Alps has continued for the past 36 hours and accumulations so far reported have been as high as a metre in one case.
It’s the second major snowfall in as many weeks, raising hopes of a bumper start to the 2014-15 ski season, which for most resorts begins in 3 – 6 weeks’ time.  It is expected some areas may now open earlier than planned.
However around 20 glacier areas are already open in Austria, France, Italy and Switzerland and it is here that the snowfall is actually being measured, with most areas reporting 20 – 60cm so far.
The main storm is expected to continue to the end of Friday, although some forecasters are saying snow will continue for the next 2 days and that up to five metres of snow can be expected on some mountains.
Most of the snow is falling above 2000m, but some resorts as low as 1500m are posting images of heavy resort level snow on social media.
