    Severe Gale-Force Wind and Heavy Rain on 11&12/11/2019

    This was the strongest wind in months. A maximum wind gust of 78.9 km/h was measured in Nadur. The severe gale-force winds and heavy rain caused disruption and some light damage. In this report, we will describe what gave rise to this intense system and how it affected the Maltese Islands.

    The intense system classified as a Mediterranean Tropical-Like Cyclone (or Medicane). Being the first one since February 2019, it formed early on Monday 11/11 and dissipated by late on Tuesday 12/11. A strong jet-stream blew a stream of very warm and humid air from over the Sahara Desert towards the western and central Mediterranean. Simultaneously, cold air from northern Europe penetrated the western Mediterranean. Both air masses clashed together, initiating the process of Mediterranean Tropical-Like Cyclone development. As a result of the clash, an existing low pressure system started intensifying very quickly, in a process referred to as cyclogenesis in meteorology. Atmospheric pressure at its centre dropped drastically, and a Mediterranean Cyclone was officially formed. The system made landfall in Algeria and lost most of its strength. Once it emerged over the very warm sea of the Gulf of Gabes, it regained strength. Its ‘eye’ was over the Sicilian Channel, close to the islands of Lampedusa and Linosa, at its closest point to the Maltese Islands.

    The cold air mass within the stormy system caused temperatures to dip all around Malta and Gozo. In fact, the temperature at our weather station in Għarb dropped by some 7°C in one hour. An outer band of convection associated with the storm system affected parts of the Maltese Islands, especially Gozo, in the mid-afternoon on Monday 11/11. At its closest point, the Mediterranean Tropical-Like Cyclone drenched the Maltese Islands with a series of heavy rain and hail showers. These lasted all day Tuesday 12/11. The storm generated waves of up to 8.0 metres.

    72.5 mm of rain were measured in the 48 hours that the storm system affected us. Għarb was the wettest locality. Thanks to this heavy precipitation, Għarb reached the monthly average for November before mid-month. The severe gale-force winds produced some light damage. The damage included uprooted trees, collapsed walls and downed power lines. A number of coastal areas suffered extensive flooding from the high waves. The ferry linking the two islands of Gozo and Malta was suspended for over 12 hours, as the very rough sea made crossing the channel too dangerous. Similarly, several catamaran journeys between Malta and Sicily were cancelled.

    Warmer but Wetter October 2019

    October air temperatures ranged from a pleasant maximum of 27.7˚C and a cool minimum of 15.7˚C. They were recorded towards the start and the end of the month respectively. With a mean air temperature of 22.2˚C, October was warmer than average. At 25.0˚C, daytime highs almost conformed with the norm. At 19.4˚C, nights were much warmer than average. Overall, temperatures were consistent throughout October, with no notable heat or cold spells.

    The 106.0 mm of rain measured last month exceeded the 83.3 mm expected in October of a typical year. More than half of October 2019’s rain fell in the last week of the month. This was the result of showers and thunderstorms produced by an unstable air mass which remained almost stationary over the central Mediterranean. The 11 days of rain and 8 days of thunder observed last month were greater than the average for this time of year. The highest 24 hour rainfall was measured at 24.6 mm on the 28th, during a set of thunderstorms. The 7th, with a total of 24.1 mm, came in at a close second. A notable pattern observed throughout October were the long periods of dry weather in between equally long periods of wet weather.

    Averaging at 7.9 km/h, the wind speed was lower than the norm by half. Weaker winds have been a dominant feature of autumn so far. The month’s windiest day was the 8th, on which a maximum gust of 59.5 km/h blowing from an easterly direction was recorded.

    Atmospheric pressure was in line with the norm.

    Stable temperatures ahead / It-temperaturi se jibqgħu stabbli

    Low pressure will persist over the western Mediterranean. Meanwhile, high pressure will prevail across the central and eastern Mediterranean. This will generate a flow of air from the south to southeast across our region. This will prevail for some days. The southerly wind will mean mild temperatures for the Maltese Islands till possibly the end of October. Temperatures will be above the average for this time of year. Maximum temperatures will hover around the 25 C mark, while lows will be of 19 C to 20 C.  Any precipitation will be in the form of isolated showers. No major rainfall events are being anticipated till the end of October.

    Warmer but Wetter September 2019

    A warmer than average September brought summer 2019 to a close. The mean temperature was calculated at 25.5°C, 0.9°C higher than the climate norm. Nights were particularly warm. Temperatures were consistent throughout September, with no extreme values. The warmest day was the 3rd with a high of 29.9°C. The coolest temperature was recorded at 18.6°C, during a thunderstorm on the 11th.

    September 2019 produced 78.4 mm of precipitation at our weather station in Għarb. The first half of the month was especially wet, with 99% of the month’s rainfall falling during the initial two weeks. The second half of the month was practically completely dry. The highest 24 hour rainfall was measured at 44.7 mm on the 10th, during a heavy thunderstorm. Another notable rainfall event this month was a thunderstorm on the 2nd. The striking feature in this particular storm was the incessant lightning that affected the Maltese Islands, particularly Gozo. There were 8 days of rain in September 2019. 4 of these were accompanied by thunder. Some hail was observed on 1 of these.

    Humidity was also low when compared to the norm. This was due to the higher than average temperatures. Another contributing factor was the plentiful sunshine that characterized the final two weeks of September 2019.

    Atmospheric pressure was in line with the norm. A relatively stable second half of the month compensated for the instability experienced in the first half of September 2019.

    The wind was stronger than usual. Despite this, no extremes were measured. The strongest gust was measured at only 48.3 km/h from the Northwest on the 7th.

    Heavy Thunderstorms on 10&11/09/2019

    A series of heavy thunderstorms were caused due to an short-wave upper-level low pressure system which passed rapidly across the central Mediterranean bringing relatively cold air over a very warm sea, creating a great deal of instability. There was plenty of moisture in the atmosphere. This produced a Mesoscale Convective System (MCS) which passed over the Maltese Islands from the late afternoon till late at night. This caused a series of heavy thunderstorms with blustery spells and also some hail, especially over Gozo. An MCS is a mass of organised thunderstorms. They take on a round or linear shape with clear-cut edges. These features distinguish an MCS from other thunderstorm structures. Highest rainfall totals from this storm were: 50.1 mm in Għarb, 40.2 mm in Xagħra, 39.7 mm in Rabat (Malta), 32.0 mm in Victoria and 25.0 mm in Nadur. Thanks to this MCS, the total rainfall in Gozo for September 2019 is already higher than the climate average for the same month. With a total of 77.7 mm, Għarb is the wettest locality so far since September 1st.

    Waterspout on 06/09/2019

    A moist and unstable atmosphere was present over the central Mediterranean, together with some wind shear (a difference in wind speed or direction over a relatively short distance in the atmosphere). A convective cloud with an intense updraft (a current of rising air) ingested and tightened a rotating layer of air. This led to the formation of a confirmed waterspout off Gozo’s northeast coast. The waterspout developed at around noon and lasted for less than 15 minutes. The same cloud produced a downpour over parts of Gozo. At least two funnel clouds were reported over the past few days. The instability that led to the formation of this waterspout was also responsible for the series of isolated thunderstorms that affected the Maltese Islands from Sunday 01/09 till Friday 06/09.

    Hotter August 2019

    The intense above-average summer heat showed no signs of cooling off in August. In fact, the average temperature exceeded the climate average of 27.1°C on a total of 26 out of 31 days. The maximum temperature for August was registered at the height of a heat spell starting in July and spanning into August, when the mercury hit 35.8°C on the 1st. The 14th and 29th, on the other hand, proved to be a breath of fresh air to the Maltese Islands, when the maximum temperature remained below 30°C. A strong wind characterised the former, whilst some rain was measured on the latter.

    Our weather station in Għarb recorded precipitation on one day, the 29th. A total of 0.2 mm were measured. This fell in a brief light rain shower. Total rainfall in August was 8.4 mm lower than average. It is quite common to experience a completely dry August.

    Humidity was also low when compared to the norm. This was due to the higher than average temperatures over the course of this month.

    Atmospheric pressure was fractionally lower than what one would expect in August. This may be attributed to the fact that two zones of low pressure affected us this month. Anticyclonic conditions dominated the rest of the month.

    The wind was also stronger than usual. This is the result of lower than average atmospheric pressure. The strongest gust was measured at 53 km/h from the Northwest on the 19th, during an unstable patch in the middle of August.

    Hotter July 2019

    2019’s July weather was characterised by air temperatures that were higher than the climate norm. Standing at 27.5°C, the mean air temperature was a solid 1.0°C higher than the norm. The average maximum temperature was calculated at 31.4°C, a marginal 0.2°C higher than the average for a normal July. The average minimum temperature, at 23.5°C, exceeded the climate value by a significant 1.7°C. Using the national criteria for a heatwave, we can say that no heat waves affected the Maltese Islands in July 2019. Several heat spells did though. The hottest day was the 9th, when the maximum temperature soared to 38.3°C. The sea offered little respite from the intense heat, as its temperature shot up to a maximum of 27°C on some days.

    Our weather station in Għarb recorded precipitation on one day, the 16th. A total of 1.3 mm were measured. This fell in a heavy rain shower which lasted for only a minute. Rain in July is rare, but not unheard of. Thunder was also heard on one day. This was in the form of a rumble or two of thunder as an isolated thunderstorm skimmed past the Maltese Islands early on the 15th.

    Humidity was also low when compared to the norm. This was due to the higher than average temperatures over the course of this month.

    Atmospheric pressure was lower than what one would expect in July. This may be attributed to the fact that three zones of low pressure affected us this month. Two of these were quite intense for this time of year.

    The wind was also stronger than usual. This is the result of lower than average atmospheric pressure. The strongest gust was measured at 51 km/h from the West Northwest on the 16th, during an unstable patch in the middle of July.

    June 2019 was the Hottest June on Record

    With a monthly average temperature of 26.1°C, June 2019 was the hottest June on record in the Maltese Islands. It broke the record set in June 2003. The average maximum temperature was calculated at 30.7°C, a solid 2.5°C higher than the average for a normal June. Nights were also rather warm. The average minimum temperature of 21.5°C was 2.2°C warmer than what one would expect in a typical June. Using the national criteria for a heatwave, we can conclude that the Maltese Islands experienced two heatwaves during this month. The first lasted for a period of four days, from 09/06/2019 to 12/06/2019. The maximum temperature measured during the first heatwave was of 37°C on 09/06/2019. The second heatwave also lasted for four days, from 21/06/2019 till 24/06/2019. The maximum temperature measured during the second heatwave was of 35°C on 24/06/2019. Despite this, it was the persistence of above average temperatures, rather than the hot temperatures themselves, that led to this June becoming the hottest on record. Another thing worth noting was the unseasonably cool first week of June. With an average temperature of just 20.9°C, the first week of June was the coolest on record.

    For the first time in a number of years, June 2019 was also completely dry. Not a drop of rain was measured at our weather station in Għarb. Thunder was not heard at any point in June.

    Humidity was also extremely low when compared to the norm. This was due to the relentless intense heat over the course of this month.

    Atmospheric pressure conformed with the mean for this time of year, as normal anticyclonic behaviour was noted.

    The wind was also lighter than usual. The strongest gust was measured at 50.0 km/h from the East Southeast on the 14th, during a brief break in between the two heatwaves.
