Hernan intensifying off Mexico
Hernan intensifying off Mexico

Tropical Storm Hernan was a short-lived tropical cyclone that caused widespread flooding and destructive mudslides across southwestern Mexico in late August 2020. The eighth named storm of the 2020 Pacific hurricane season, Hernan formed to the southwest of Mexico on August 26. The cyclone peaked with maximum sustained winds of 70 km/h (45 mph) and a minimum atmospheric pressure of 1001 mbar (hPa; 29.56 inHg) before passing just offshore western Mexico and dissipating in the Gulf of California. Despite not making landfall, Hernan dropped extremely heavy rainfall across several states, peaking at nearly 610 mm (24 in) in Jalisco. More than 305 mm (12 in) of rain fell across the Costa Grande of Guerrero from August 24 to 27. A total of 1,674 homes and 9 schools suffered severe damage. A man died after falling off his roof while checking for storm damage. The cyclone caused MXN$594.05 million (USD$26.91 million) in damage across seven states along the Pacific coast of Mexico.

Two species of sea urchin

Sea urchins are a group of spiny globular echinoderms which form the class Echinoidea. About 950 species live on the seabed, inhabiting all oceans and depth zones from the intertidal to 5,000 metres (16,000 feet; 2,700 fathoms). Their tests (hard shells) are round and spiny, typically from 3 to 10 centimetres (1 to 4 inches) across. Sea urchins move slowly, crawling with their tube feet, and sometimes pushing themselves with their spines. They feed primarily on algae but also eat slow-moving or sessile animals. Their predators include sea otters, starfish, wolf eels, and triggerfish. This photograph, taken off the northern coast of Haiti near Cap-Haïtien, shows two species of sea urchin: a West Indian sea egg (top) and a reef urchin (bottom).
