Hurricane Preparedness: Offshore Operations

Tropical cyclones have significant impacts on marine operations worldwide. Prior to experiencing tropical cyclone threats, offshore facilities must secure equipment, shut-in wells, and evacuate personnel. Operations can remain shut down for extended periods in the event that an offshore platform or rig is damaged or destroyed. Damaged pipelines along the seafloor are a common cause of interruptions to oil and gas supply.

To prevent structural damage and spills, control costs, and ensure the safety of personnel, accurate weather forecasts and advanced notification of tropical hazards are paramount. Even a weak tropical cyclone can produce hazardous weather conditions and put coastal and offshore operators at risk. Be sure to determine your exposure to the risks associated with tropical cyclones before the start of this Atlantic hurricane season.

Wilkens Weather provides a suite of online and mobile tracking tools to warn our customers of these risks. To be confident that you’re prepared this hurricane season, trust in the tropical expertise and tools provided by WWT: Read More »

2015 Holiday Storm Retrospective

A powerful storm system tracked across the northern Great Plains this holiday season. Heavy snows and blizzard conditions were observed in the Dakotas, strong storms occurred in Kansas and Missouri, and an ice storm developed in areas between. Of significant note was a tornado report in Kansas that if confirmed would be the first tornado recorded on Christmas day in that state. In addition, wind gusts in excess of 70 mph were reportedIowa Environmental Mesonet Wind Speed Reports December 2016 in northwestern Iowa, causing structural damage in the area. These conditions are a stark reminder that like meteorologists, Mother Nature does not take the holidays off. Interestingly, a similar storm system impacted the southern plains last holiday season.

One year ago, a major storm system moved from Texas through the Great Lakes, capping off a year filled with extreme weather in Texas and beyond. Read More »

Northern Hemisphere’s ‘Shortest’ Day of The Year

Winter Solstice is upon us…

The winter solstice is a single moment in time when the Sun is exactly over the Tropic of Capricorn in the Southern Hemisphere. This year that moment occurs on December 21st at 1044UTC or 4:44AM CDT.

A common misunderstanding with the winter/summer solstice regards the Sun’s distance from Earth. Distance does not create the seasons, the tilt of the Earth does. Earth’s 23.5° tilt is the reason each hemisphere receives various amounts of sunlight from season to season. The winter solstice marks the day the North Pole is tilted furthest away from the Sun.Read More »

Harmattan Dust in West Africa

As we approach the end of the calendar year, meteorologists, once again, encounter a significant weather phenomena that can sometimes be a challenge to forecast: The Harmattan Winds.

Harmattan winds are derived from a dry and dusty, northeasterly trade wind that originates in the Sahara. As the monsoon trough shifts south during the boreal winter, the trade winds will travel further south reaching the West Coast of Africa. This type of wind is strengthened by low pressure over the north coast of Guinea and high pressure over Northwest African Journal of Environmental Science and Technology Harmattan DustAfrica. The Harmattans can carry desert dust into the Atlantic and the Gulf of Guinea leading to hazardous operations on and offshore. Another element to the strength of the Harmattan is eastward movement of a low pressure system over Europe and its subsequent surface cold front that will move over the Mediterranean into North Africa. While the cold air will mix and warm over Africa, the wind will continue to surge south carrying with it the blinding dust covering everything in its path. Crop soil from the Sahel, the region between the Sahara desert and humid savannas, can also be mixed up in the winds further dropping visibility.Read More »
