DISCUSSION: As a fairly strong low-pressure system quickly passed through Central and Eastern South America only a few days ago, there was intense lift and warm-air advection occurring. This combination of advection and lifting of warm/moist air led to a prolific rainfall event across Southern Brazil which dumped an average of 42 mm of rainfall across a large portion of the city of Porto Alegre and it persisted for several hours on the morning and afternoon of 15 May. Though the weather has become more settled since then across this part of Brazil, much flooding is still subsiding due to the heavy rainfall which collected in particularly lower-lying areas. Note the eye-grabbing lightning strike captured in the photo linked below which was associated with one of the stronger storms which moved through Porto Alegre!

DISCUSSION: As clear to partly cloudy skies predominated during the early to mid-afternoon hours today in and around Caracas, Venezuela, the combination of assorted ice particles at the right angles higher up in the atmosphere and the proper reflection and refraction of sunlight off of these ice particles helps to create what was observed as a 22° halo! Note the assortment of colors that is created through the process of light refraction in the upper atmosphere!

DISCUSSION: As a disturbance moved through parts of the Yucatán Peninsula (particularly those areas across the eastern half of the peninsula), strong storms erupted some of which develop substantial rotation including the supercell time-lapse from Cancun Mexico as captured earlier this afternoon! Note how as the storm moved over this particular beach you can identify what appears to be the bounded weak echo region (BWER) based on the region within the core of the storm where you can partially see some clearing! Very neat stuff to down in Eastern Mexico! For more neat high-impact weather content from across Central America, be sure to click here!
DISCUSSION: As strong thunderstorms erupted much earlier yesterday morning over parts of Venezuela, some very impressive lightning striks unfolded with some of the more intense storms. As captured in the beautiful image below, this was just one classic example of a cloud-to-ground lightning strike directly over Lake Maracaibo located in Northwestern Venezuela! Being as though lightning is one of the number one killers among the various dangers from thunderstorms anywhere in the world.
