The subtropical depression off the coast of #Brazil has become a tropical depression as convection increases near its center. It is likely to become a tropical storm ( #Akar á) on Monday as it meanders. This is the first fully tropical cyclone in the South Atlantic since 2009.

A possible harbinger of the #hurricane season to come: although the ITCZ is currently in its normal springtime position near the equator, it is VERY convectively active due to anomalously warm SSTs. Those warmer SSTs should creep north along with the ITCZ in the next few weeks.

#StormDaniel , a low in the Mediterranean Sea SW of Greece, appears to have subtropical characteristics ( #medicane ), with a compact wind field and convection increasing N of center. This was well fcst by the models, and it could become a bonafide TC as it moves SE toward #Libya .

WPAC: Invest #90W (91W is gone) is starting to show signs of consolidating as it meanders SE of Yap. This system could become a tropical depression as it moves WNW toward #Palau . The #Philippines should monitor this as it's too early to say what, if any, impact there could be.

TD #AghonPH ( #93W ) is continuing to consolidate as it approaches the island of Samar. Its circulation remains fairly broad but convection has increased near the center. It is likely to become a tropical storm tomorrow despite crossing some land areas in the #Philippines .

#Beryl ( #02L ) is starting to regain some strength. Radar from Brownsville shows a partial eyewall, although some dry air remains entrained within the circulation. Improved outflow from a trough to the north and increased moisture is aiding convective development. #txwx 1/

Tropical Storm #Alberto ( #01L ) has arrived, and it will soon make landfall in NE #Mexico . It's not winning any beauty contests, but it will dump tons of rainfall on portions of SE Texas (mainly S of I-10) and northern Mexico, with totals of over 10" possible in some areas.

A large area of low pressure - invest #90P - is quickly getting better organized as it moves slowly southwestward toward #Queensland . 90P is expected to become TC #Kirrily by tomorrow and could reach severe TC strength before landfall near #Townsville late Thursday night.

An animated closeup of #Beryl 's ( #02L ) eye as it approaches #Grenada and St. Vincent and the Grenadines, particularly the island of #Carriacou . Note the pinwheel-like mesovortices within the eye, a sign of extreme instability, and likely another indication of strengthening.

After performing a cyclonic loop off the eastern coast, #Typhoon #Gaemi ( #05W / #CarinaPH ) has finally made landfall near Nan'ao in #Taiwan 's Yilan County. The typhoon is weakening due to the rugged terrain but is producing a prodigious amount of rainfall across the island.

#HurricaneHilary ( #09E ) continues to rapidly intensify southwest of Mexico, and is now a Cat 3 #hurricane with winds of 120 mph. Continued RI is likely and #Hilary could become a Cat 4 later tonight. Tropical storm watches could be required for #SoCal soon. Unprecedented.

In the Western Pacific, no tropical cyclone activity is likely during the next week. Some tropical waves could bring a little bit of badly needed rain to the #Philippines later this week, while an unsettled pattern continues for #Okinawa and the Ryukyu Islands.

When the schools don't close for dangerous weather: "that's dumb, you should close, it's not safe for the kids" When the schools *do* close for dangerous weather: "you're closing for a little rain, that's dumb, we walked to school in blizzards and turned out fine" #RVA #VAWX

#Lanyu /Orchid Island is now within the eye of #Koinu ( #JennyPH ). The island has seen some extreme wind gusts, as high as 180 kts, mainly due to its high elevation (325-350 m). Although they are not representative of winds at the surface, Koinu is likely stronger than advertised.

Invest #90W is up for the disturbance southeast of #Yap and #Palau . This system has a fairly decent chance to consolidate into the first tropical cyclone of the 2024 season by the end of the week. Palau and the #Philippines should monitor.

#Ewiniar ( #01W , #AghonPH ) has undergone even more explosive intensification despite close proximity to rugged terrain in #Luzon and is now a high end Cat 1 #typhoon . Good news is it should pull away from Luzon soon and head out to sea. 1/

#Beryl ( #02L ) is moving away from #Jamaica and will soon pass south of the Cayman Islands. It remains a Cat 4 #hurricane with 115 kt (130 mph) winds. Wind shear is taking its toll on the system, and despite the core hanging on, the CDO is eroding and the eye is less distinct.

#Beryl ( #02L ) continues to strengthen, and its winds have increased to 135 kts (155 mph). I am still confused because recon obs and Dvorak estimates support Cat 5 status, including a 140 kt dropsonde ob. Beryl's got about 12 hours left before shear dramatically increases.

#Beryl ( #02L ) is now the first June major #hurricane on record east of the Windward Islands, packing winds of 115 kts (130 mph, Cat 4). It has a very impressive satellite presentation with a clear eye w/stadium effect and strong radial outflow. Further strengthening is likely. 1/

The low in the E Atlantic now lies as a naked low cloud swirl, ending its development chances. However, this little low could have a big impact as its inflow has weakened the easterly trades, which could contribute to even more warming of the already high SSTs in the MDR.

EPAC: #Jova ( #11E ) is now just shy of Category 5 intensity, with winds up to 135 kts. I strongly disagree with this as it's based on a T7.0 SSD Dvorak fix and a T6.5 TAFB Dvorak fix where they opted not to break the technique's constraints. Given the average FT...why? @NHC_TAFB

The tropical depression currently moving across #Samar in the #Philippines ( #AghonPH , formerly #93W ) has finally been designated Tropical Depression #01W by JTWC - it's the first numbered tropical cyclone in the Northern Hemisphere in 2024. It continues to be a messy rain event.
