UPDATE: Hurricane Florence remains on track – intense landfall likely in North Carolina on Thursday

Severe Weather Europe - 11. September 2018 - 16:28

A Category 4 hurricane Florence continues on track with previous simulations, it is slightly weakened but its forecast track should bring it into North Carolina on Thursday. Latest satellite imagery revealing a cloud-filled eye with an inner eyewall collapsing and outer eyewall developing. This is a sign of the eyewall replacement cycle on going – once it is completed, the outer eyewall will dominate and bigger eye is likely to appear and hurricane will begin strengthening again. Latest NOAA Hurricane Hunters pass through the hurricane revealing very intense wind field in the SW and SE quadrants and slightly higher pressure compared to yesterday. Florence will begin deepening in few hours when an eyewall replacement cycle will be completed. Would not […]

UPDATE: Florence is now a dangerous Category 4 hurricane

Severe Weather Europe - 11. September 2018 - 0:36

As expected in our morning update on the dangerous hurricane heading towards the Carolinas (US), Florence now continues with rapid strengthening and is now already a very dangerous Category 4 hurricane – officially with sustained winds of 138 mph and central pressure of 939 mbar. Florence is expected to remain a major hurricane for the next 3 days and chances are, it gets upgraded into a Category 5 within the next 48 hours due to very favorable conditions for further intensification. Very low shear is supporting an upper-level outflow while extremely warm sea surface temperatures give huge amount of ‘fuel’ for intense thunderstorms in the eyewall. Latest satellite imagery revealing an impressive structure of powerful eyewall with textbook stadium effect […]

Heat wave across parts of Europe this week – Sept 10-16, 2018

Severe Weather Europe - 10. September 2018 - 17:07

Very warm weather with temperatures up to and locally even well over 30 °C is expected across parts of Europe this week. We take a detailed look. In response to the favourable pattern evolving across Europe, much of the southern half of the continent will be enjoying very warm weather over much of this week. Temperatures are expected to push into upper 20s, surpassing 30 °C in many places in southern Europe, including parts of Spain, France, Italy, Slovenia, Hungary, Croatia, Serbia, Romania, Bulgaria and parts of extreme southeastern Europe as far as western Turkey. Parts of Spain are expected to push into upper 30s, close to 40 °C in the middle of this week. Refer to maps below for […]

Dangerous hurricane Florence heading towards the Carolinas, USA

Severe Weather Europe - 10. September 2018 - 16:21

The intensifying hurricane Florence is a Category 2 hurricane now, with sustained winds of 105 mph and central pressure of 969 mbar. Based on the latest satellite presentation, additional rapid strengthening is expected through the next 24-36 hours as near-ideal conditions are present ahead of Florence’s path – almost no wind shear and extremely warm sea surface. The hurricane’s shape is becoming symmetrical and the eyewall is becoming stronger with a distinct eye visible. We can expect Category 4 strength by tomorrow morning, Tuesday Sept 11th. This is the official NHC forecast path of hurricane Florence: it is becoming increasingly likely that landfall will occur into the Carolinas, where Florence will hit as a major hurricane of at least a […]

Weekly pattern across Europe overview (Sept 11 – 18th)

Severe Weather Europe - 10. September 2018 - 15:39

Our continent will mostly be dominated by a strong ridge across south-central Europe this week, while deep systems with dynamic weather are expected across the northern parts of the continent. The main features of interest will be a large upper low over SE Europe and a weak upper low on the western side of the omega blocking ridge, over the Iberian peninsula. Tuesday – Sept 11th Early this week, the pattern is characterized by a strengthening upper ridge from western into central Europe and a deep trough over the N Atlantic. This will bring much warmer weather again. Two weak upper lows are the focus for convective weather: one is over the Iberian peninsula and the other one is the […]

More severe thunderstorms with torrential rainfall in southern and eastern Spain today – September 9, 2018

Severe Weather Europe - 9. September 2018 - 14:24

Another day of severe thunderstorms with torrential rainfall is expected for parts of southern, central and eastern Spain today. The Iberian peninsula is under the influence of a shallow, but persistent and virtually stationary cutoff upper low. Significant instability builds up, particularly over the sea and in the coastal area as surface easterly winds provide warm, moist air advection from the sea. Further slow-moving storms are expected to form across southern and eastern Spain, with peak threat for torrential rainfall and flash floods. Other threats include large hail, intense straight line winds and waterspouts. Overview of cloud cover and precipitation over the Iberian peninsula.

Tropical storm Florence could impact east US coast next week

Severe Weather Europe - 7. September 2018 - 16:18

It is the peak of the hurricane season and the Atlantic is becoming active. A rapidly developed system formed the hurricane Florence, which intensified into a Category 4 hurricane on Wednesday. It reached the lowest pressure of 953 mbar and peak sustained winds of 130 mph. Hurricane Florence then interacted with an area where significantly sheared environment was present, weakened and collapsed. It is currently a Tropical Storm with sustained winds of 65 mph and central pressure of 996 mbar. Florence is heading further west and is expected to arrive into better non-sheared environment in the next days, so an intensification is likely. It is much too soon to know how Florence may impact the US later next week, if […]

Invasive pines fueled 2017 fires in Knysna, South Africa

ScienceDaily - 6. September 2018 - 17:04
The replacement of natural fynbos vegetation with pine plantations in the southern Cape in South Africa, and the subsequent invasion of surrounding land by invasive pine trees, significantly increased the severity of the 2017 Knysna wildfires. Over four days in June 2017, the Knysna fires burnt 15000 hectares, claiming the lives of seven people and destroying more than 5000 hectares of commercial pine plantations and over 800 buildings.

California: Global warming, El Niño could cause wetter winters, drier conditions in other months

ScienceDaily - 4. September 2018 - 22:04
New research indicates that what future precipitation California gets will be pretty much limited to the winter months -- think deluge-type rainfall rather than snow -- and non-winter months will be even dryer than usual, with little or no rain at all.

Weekly pattern overview across Europe (Sept 3 – 10th, 2018)

Severe Weather Europe - 3. September 2018 - 18:18

Here is an overview of the pattern evolution this week. Early September across our continent will be characterized by ridging over northern Europe while some more dynamic weather is expected further south across central and southern Europe. The overall pattern will bring above normal temperatures across much of our continent while below normal temperatures are likely over western Europe and the Iberian peninsula where troughs and frontal systems will be ongoing. Monday, Sept 3rd A large, but weakening upper low remains over the northern Mediterranean, expected to diminish while moving onto the Balkan peninsula overnight. Strong ridging remains over Scandinavia where stable weather is expected. A weak upper low is entering SW Iberian peninsula and brings a widespread storm development […]

Severe thunderstorms likely in eastern and northeastern Spain today – September 3, 2018

Severe Weather Europe - 3. September 2018 - 16:07

A broad cutoff upper low is located over the Atlantic just west of the Iberian peninsula. Ahead of the low a significant overlap of instability and shear is building up an environment conductive for the formation of severe thunderstorms. We take a closer look. A moderately strong subtropical jetstreak rounds the southern edge of the cutoff low, passing over southern and eastern Spain and the Balearic Islands. Winds up to 30-40 kt are present at 500 mbar level. Moderate to locally strong instability is building up, as easterly surface winds advect moist air from the western Mediterranean. Various models are in good agreement that up to 2000 and locally up to 3000 J/kg MLCAPE will build up in eastern Spain, […]

Very warm period for N-NE Europe early next week, Sept 2-5th

Severe Weather Europe - 30. August 2018 - 16:46

A very warm period is foreseen for northern Europe after this weekend. Temperatures up to almost 10 °C above average for early September are possible across parts of Finland. As mentioned in the weekly preview yesterday, the European continent is undergoing a significant pattern change this weekend. A so-called Rex blocking ridge pattern develops: a persistent strong ridge / high pressure system over north Europe with an upper low to its south in the Mediterranean. Strong warm advection will be ongoing along the eastern flank of deep trough over the north Atlantic onto Scandinavia. This then brings stable and warm weather into N-NE European countries and much warmer afternoons than usual. Warm weather is expected to continue for several days […]
