Storm Lorenzo October 2019 Storm Lorenzo brought strong winds to the west of Ireland on 3 October 2019 before crossing the UK on 4 October. Lorenzo was a mid-Atlantic hurricane but weakened rapidly as it tracked north-east past the Azores toward the west coast of Ireland. The storm followed a spell of unsettled wet weather across England and Wales during late-September. Impacts The persistent wet weather during late September caused some localised flooding problems, while heavy rainfall on 1 October brought severe flooding to the village of Laxey on the east coast of the Isle of Man. Torrential downpours across parts of Wales, the Midlands and southern England on 1 October also brought localised flooding and disruption. Storm Lorenzo tracked across the UK during 3 to 4 October 2019. The storm mainly affected the west of Ireland, with limited impacts across the UK. Weather data The analysis chart at 1800 UTC 30 September 2019 shows fronts pushing slowly north-east, bringing persistent heavy rain to western areas of the UK. The rain-radar images at 1630 UTC 30 September 2019 and 0830 UTC 1 October 2019 show heavy rain across north Wales, northern England, southern Scotland and the Isle of Man. On 1 October, thunderstorms also brought some torrential rainfall across parts of the Midlands, Wales and southern England. The map below shows rainfall totals for the 10-day period 21 to 30 September 2019. The weather was generally mild, wet and unsettled with a succession of low pressure systems bringing significant rainfall to England and Wales. Upland areas in the west recorded over 200mm (an average of 20mm per day). The wet weather followed a much drier spell through the middle of the month. The analysis chart at 0600 UTC 2 October 2019 shows Hurricane Lorenzo located near the Azores. Lorenzo weakened rapidly as it moved north-east toward Ireland The analysis chart at 1800 UTC 3 October 2019 shows Storm Lorenzo located to the west of Ireland. The map below shows maximum gust speeds on 3 October 2019. The strongest winds were across the west of Ireland, but gusts reached 40 to 50Kt (46 to 58 mph) across parts of Northern Ireland and south-west Scotland.

Four different quality categories from Wikipedia were chosen, from the total amount of eight, to ensure gathering of a representative sample, for each category there are fifty sentences, the total amount of the sentences altogether is, therefore, two hundred. The sentences will be analysed according to the Firabsian theory of functional sentence perspective in order to discriminate differences both between the quality categories and also within the categories.

AOML Keynotes NOAA’S ATLANTIC OCEANOGRAPHIC AND METEOROLOGICAL LABORATORY April-June 2020 AOML is an environmental laboratory of NOAA’s Office of Oceanic and Atmospheric Research located on Virginia Key in Miami, Florida Gliders Deployed to Obtain Ocean Observations for Hurricane Studies and Forecasts NOAA and US Navy hurricane gliders were deployed in July off the coasts of Puerto Rico, the Gulf of Mexico, and US eastern seaboard to improve the representation of the upper ocean in numerical models used for hurricane forecasts. These sturdy unmanned gliders will measure temperature and salinity down to a half mile below the ocean surface. They operate in hurricane conditions and have even survived shark attacks as they collect and transmit their data via satellite. During the 2019 Atlantic hurricane season, the gliders collected approximately 100,000 ocean profiles. For the 2020 Atlantic hurricane season, NOAA, the US Navy, US Integrated Ocean Observing System (IOOS), IOOS Regional Associations, and academic partners will conduct approximately 30 glider missions that are expected to obtain 50 percent more ocean profile data AOML researchers and partners with the Cooperative Institute for Marine and compared to previous years. This is possible given enhanced Atmospheric Studies at the University of Miami and CARICOOS deployed 11 support by NOAA and the ongoing and increased collaboration underwater ocean gliders in July to collect data in support of improved hurricane among glider partners. forecast models. Image credit: NOAA/CIMAS/CARICOOS. To prepare for the 2020 hurricane season, AOML scientists trained new glider pilots and technicians from partner institutions crucial for helping NOAA continue the hurricane glider project in in Puerto Rico, the Dominican Republic (Maritime Authority, 2020 despite uncertainties related to the COVID-19 pandemic.

Chubb Are You Disaster Ready? White Paper 7.09.20
Are You Disaster-Ready? What You Need to Know Before Hurricane Season Introduction In 2019, Chubb published a White Paper entitled “Staying Ahead of the Storm: Preparing for Upcoming Hurricane Seasons,” which noted that major hurricanes during the two previous years, 2017 and 2018, caused storm-related damage totaling hundreds of billions of dollars, while at the same time outlining the lessons learned for mitigating hurricane losses in the future. The 2019 hurricane season was not nearly as costly as the previous two. However, hurricanes in 2019 did cause above-average property damage for the fourth year in a row1, highlighting the critical importance of applying risk management lessons learned from year to year. 1 Are You Disaster-Ready? What You Need to Know Before Hurricane Season The 2019 Storm Season At the same time, Hurricane Barry pummeled Louisiana as a Category 1 Impact of the The 2019 hurricane season was also the storm, dropping heavy rainfall in that 2019 Storm Season fourth most active on record for named state as well as Arkansas, and costing Atlantic storms.

Fall/Winter 2007
St rm Signals Houston/Galveston National Weather Service Office Volume 76 Fall/Winter 2007 Houston/Galveston Meteorologist In Charge - Bill Read Detailed to National Hurricane Center In August, I was given the unique opportunity to serve as Acting Deputy Director of the Tropical Prediction Center/National Hurricane Center (NHC) for an as yet to be determined period of time beginning Labor Day. This came about when the Director position became vacant and Dr. Ed Rappaport, the current Deputy Director, was elevated to Acting Director until such a time as the vacancy can be filled through the competitive process. My duties are to administer some ten actions that arose from the report of a Management Assessment Team which looked at the operation during late June and early July. Operationally, I will oversee the activities of the Hurricane Liaison Team (HLT). Gene Hafele and I have served as meteorologists on the HLT a number of times over the recent past, hence this was a natural task for me to take on. As of this writing (September 17th), I have been on the job only two weeks, but a lot of interesting events have happened. Operationally, NHC covers all systems in the Atlantic and Eastern Pacific, so almost every day this time of year there is either a storm or suspect area requiring our attention. In addition to the well known tropical cyclone warning process, another branch, known as the Tropical Analysis and Forecast Branch, works 24/7 producing forecasts and analyses of the tropical Atlantic and eastern Pacific oceans. Detailed analysis maps are produced and sent to the marine community, as are high seas and offshore wind and seas forecasts, similar to the coastal waters forecast we produce at the local forecast office.
