Meteorologists often refer to the right side of a hurricane as the “dirty side” of the storm.

This year, a blue moon will fall on Halloween -- and it’s the first blue moon we’ll experience since the last one on March 31, 2018. A blue moon, in case you’re wondering, isn’t blue in color at all — unless you’re talking about the other blue moon, which we’ll fill you in on shortly. A blue moon, by the most popular definition, according to meteorologist Paul Gross, is when two full moons appear in a single month. “We will have full moons on Oct. 1 and 31, so that means that we’ll have a blue moon on Halloween,” Gross said. The full moon to follow on the last day of the month then becomes a Halloween blue moon.

Louisiana residents who are still recovering from the devastation of a powerful hurricane less than two months ago braced for another hit as Hurricane Delta steamed north through the Gulf on Thursday after swiping Mexico’s Yucatan Peninsula, the Associated Press reported. “They do not retire Greek alphabet storm names -- at least so far,” Gross said. The last time we went through all the letters of the alphabet and moved on to the Greek alphabet was 2005. In 2005, a record-breaking year of devastating hurricanes, we made it through six Greek letters. The Committee also agreed that it was not practical to retire into hurricane history a letter in the Greek alphabet.

Mars will appear brighter than at any other point during the year on Oct. 13, when it will be closest to Earth. “So, a little over every two years, Mars and Earth are closest together in their orbits and, thus, Mars is at its brightest in our nighttime sky.

A blue moon, by the most popular definition, according to Gross, is when two full moons appear in a single month. “We will have full moons on Oct. 1 and 31, so that means that we’ll have a blue moon on Halloween,” Gross said.

But regardless where you’re located or what types of weather your region regularly experiences, it’s always best to remain vigilant. When it comes to hurricanes and big storms, there’s always so much talk about how to prepare the insides of our homes. Therefore, it’s always better to err on the side of caution, he added. “There’s nothing wrong with being too careful.”So, the next time a big storm’s coming to town, walk around the exterior of your house, your property or your yard. You could even turn this into a project, moving just a few belongings a day, leading up to the storm.

For those who will be witnessing totality during the Great American Eclipse on Monday, you’re in for a real treat: not only will you see the sun completely blocked by the new moon -- so long as it’s not cloudy -- but it will get eerily dark. Birds may become confused or stop flying. And if you know where to look, you may even be able to spot a hidden planet.

(GMG) – Could the total solar eclipse set for Monday be rained out? You’ll see totality or the partial solar eclipse, depending on where you are, without any problem. But if it’s cloudy and you’ve traveled for the total solar eclipse, prepare for disappointment. “Basically, to be able to see the sun eclipsed by the moon, it has to be clear out,” Gross said. Last week, we showed you several maps predicting the states that would see clear skies during Monday’s solar eclipse.
