Storms and Floods

Tropical Storms

Tropical cyclone Gillian is located approximately 162 nm east-northeast of Mornington Island, Australia. The final warning on this system has been issued by the joint typhoon wrncen Pearl Harbor hi. However, available model guidance suggests there is a possibility that the system will redevelop over the southern coast of the Gulf with moderate tropical cyclone intensity within the next 24 to 48 hours.

Fishermen in Australia pin hopes on Tropical Cyclone Gillian. Fishermen in the Gulf of Carpentaria are hopeful Tropical Cyclone Gillian will bring heavy inland rain, flushing out rivers to provide food for ocean fish.

Tropical cyclone Lusi is located approximately 408 nm north of Noumea, New Caledonia. Lusi has spawned warnings and watches in the Solomon Islands.

Tropical cyclone Hadi is located approximately 514 nm north of Brisbane, Australia.

Volcanos

Roundup of Global Volcanic Activity:

Etna (Sicily, Italy): While weak lava effusion and sporadic strombolian explosions from the New SE crater continue with little changes, the Bocca Nuova crater has started to produce occasional small ash emissions of sometimes elevated temperature (suggesting presence of magma near the surface).

Popocatépetl (Central Mexico): Activity has been low with less than 1 emission per day and no recent explosions.

Today’s seismogram shows the magnitude 6.3 earthquake in southern Mexico early this morning.

Pacaya (Guatemala): According to INSIVUMEH, lava continues to flow from the vent (on the western base of the cone?), but is mostly inside small lava tubes. Strombolian activity at the summit vent seems to have decreased or ceased.

Fuego (Guatemala): A small lava flow continues to be active on the upper SE slope of the volcano. Explosions have been a bit weaker on average, with incandescent lava ejected to 150 m and ash plumes reaching 500-800 m above the summit.

San Miguel (El Salvador): NO significant changes in activity have been noted. Seismic activity remains elevated, but at stable levels lower than during the second half of February.
