News Tropical Storm Erick likely to grow into hurricane en route towards Hawaii
•(Reuters) – Tropical Storm Erick in the eastern Pacific is likely to grow into a hurricane soon, possibly reaching Category 3 strength by Tuesday as it churns closer towards Hawaii, but it is expected to begin weakening later in the week, forecasters said on Monday.The latest advisory from the U.S. National Hurricane Center put Erick’s centre at about 1,200 miles (1,945 km) east-southeast of Hawaii’s Big Island, the easternmost edge of the U.S. archipelago state, still too far away to pose any threat to land.Packing maximum sustained winds near 70 miles per hour (110 kph), Erick was poised to reach hurricane strength imminently, and could grow by Tuesday into a major hurricane, defined as a Category 3 on the five-step Saffir-Simpson wind scale, according to the latest forecast.Erick would be the third hurricane in the eastern Pacific this season.”A weakening trend is expected to begin later in the week,” the hurricane centre advisory said.A tropical storm becomes classified as a Category 1 hurricane when its top sustained winds reach 74 mph (119 kph). Sustained wind speeds of at least 111 mph (178 kph) make it a Category 3.The weather system is expected to weaken back into a tropical storm by the time it makes its closest approach to Hawaii, with Erick forecast to skirt south of the Big Island on Friday morning. Forecasts call for a higher chance of gale-force winds from the storm on the Big Island later this week.Another tropical storm, dubbed Flossie, was trailing Erick farther out in the eastern Pacific.(Reporting by Steve Gorman in Los Angeles; Editing by Sandra Maler)
„Even if the center of the storm passes south of the state some impacts from the storm may extend well north of the low center,” the National Weather Service in Honolulu said.”For now, we are forecasting an increase to moisture levels, clouds and showers; starting over the Big Island by late Thursday and spreading westward to the smaller islands into the weekend,” the weather service said.As of 5 p.m. ET Monday, Erick was located about 1,205 miles east-southeast of Hilo, Hawaii. It had maximum sustained winds of 70 mph and was moving west-northwest at 16 mph.A tropical storm becomes a hurricane when its winds reach 74 mph.Erick would become the third hurricane of the 2019 East Pacific hurricane season, following Alvin and Barbara, AccuWeather said.Another system, Tropical Storm Flossie, was also spinning in the eastern Pacific Ocean. It was centered about 830 miles south-southwest of the southern tip of the Baja California Peninsula and was moving west at 18 mph. The storm had maximum sustained winds of 50 mph, though it too was projected to grow into a hurricane on Tuesday or Tuesday night.Flossie could take a similar or perhaps even more northerly track than Erick, AccuWeather said. This could put Hawaii in the forecast path of Flossie by early next week.Closer to the U.S. mainland, forecasters were watching a system in the Caribbean Sea that has a 10% chance of becoming a tropical depression or storm within the next five days.This system is expected to move west-northwestward across the Caribbean and the Greater Antilles during the next few days, bringing locally heavy rainfall and possibly some flooding across portions of these islands, the hurricane center said.On Puerto Rico, the rain would be welcome as it could help alleviate drought conditions there.By week’s end, the system should be near Florida or the Bahamas.Contributing: The Associated PressThis article originally appeared on USA TODAY: Tropical Storm Erick could graze Hawaii by week’s end
Some of you have been asking about the widespread radar returns the past few nights in #Vegas. Radar analysis suggests most of these echoes are biological targets. This typically includes birds, bats, and bugs, and most likely in our case–> Grasshoppers. #VegasWeather
While some of the activity in the northern sector of the radar display included rain, a majority of the green coloring in the southern half of the Las Vegas represented an insect invasion so large it registered on weather radar.
“Haven’t seen something like this in a long time,” Guillet said.
Grasshopper invasion: Grasshoppers are invading Las Vegas. And they might not leave for weeks
The National Weather Service upgraded its radar system in the spring of 2012.
Enhancements made the service’s weather sampling capabilities much more sensitive, able to differentiate between large raindrops, small raindrops – and sometimes even biological entities.
The most common „biological targets” captured on weather radar in Southern Nevada are birds and bats.
Grasshoppers on the move
A wet spring expedited the insect swarm’s northern migration, but the bugs are not dangerous.
„They don’t carry any diseases, they don’t bite, they’re not even one of the species that we consider a problem,” said Jeff Knight, an entomologist with the Nevada Department of Agriculture. „They probably won’t cause much damage in a yard.”
The grasshoppers are attracted to ultraviolet light. That’s why the insects are often found swarming glowing bulbs of white light.
The jumpy bugs are likely to remain in transit across Southern Nevada over the next several weeks, Knight said.
The state has records as far back as the early 1960s of Nevada grasshopper invasions. In three decades as an entomologist, Knight has seen the insects visit southern Nevada four or five times.
In 2010, state agriculture officials gear up for a springtime invasion of crop-eating grasshoppers in northern Nevada.
